The article presents the results of the research obtained studying the dynamics of some indicators of endometritis in symptomatic infertility. The research was carried out at the Department of Obstetrics, Surgery and Physiology of Domestic Animals of the Don State Agrarian University in Persianovsky settlement, Oktyabrsky district, Rostov region. It was found that with latent endometritis, the most significant changes in the number of erythrocytes in 1 ml of blood were fixed with a minimum coefficient of variation (5.67–6.07); the platelet content in latent endometritis in cows compared to physiological norms for clinically healthy animals decreased by 26, 6%, and with chronic endometritis by 39.6%. The number of erythrocytes in cows with latent endometritis decreased by 1.1 times and in infertile cows with chronic endometritis – by 1.3 times compared to physiological norms typical for clinically healthy animals. Also, increased glucose content at this stage indicated a high level of bioenergetic processes in the body of cows, which proves its good protective forces. But a significant deviation was noted in the indicators of gluconeogenesis: with latent endometritis – by 1.15 times, with chronic endometritis – by 1.29 times (p < 0.01). The content of cholesterol in the blood was higher in cows with chronic endometritis, regardless of the form of its occurrence, in comparison with clinically healthy cows (p < 0.05), and the concentration of cholesterol in chronic endometritis was slightly higher than in latent endometritis (p < 0.05).

An important problem in organizing full-fledged feeding of cows is to establish the optimal level of energy nutrition, taking into account productivity, age and lactation period. The studies were carried out in the conditions of the foothill zone of the North Caucasus. 45 first-calf cows of the Schwyz breed were selected, from which three groups (15 heads in each) were formed according to the principle of pairs of analogues, taking into account age, live weight and body condition. The animals of the first group were control animals, and they received a diet that corresponds to the detailed norms (2003) of the All-Russia Institute of Animal Husbandry (ВИЖ). The rations for first-calf cows consisted of leguminous-cereal hay, corn silage, herb haylage, and compound feed. The basic feeds of the diet were given in equal amounts to cows of all groups. The second and third experimental groups during the period of milking received rations in which the level of energy supply was increased by 10 and 20%, respectively. Corn fodder meal was used as additional feeding. In terms of nutritional value, this was 0.92 and 1.84 EFU (0.7 and 1.4 kg), respectively. It was found that the introduction of an additional dose of energy feed (10 and 20% of corn flour) into the feeding ration of experienced first-calf cows contributed to an increase in milk yield in the first 100 days of lactation by 11.5 and 14%, respectively, as well as to some improvement in the quality indicators of milk. For example, in terms of milk fat content, cows from the experimental groups exceeded the control group by 0.06–0.08%, and in terms of milk fat yield, the difference between the groups was 10.9–16.6 kg. The protein content is 0.04–0.08%. The difference in the yield of milk protein is 9.1–14.9 kg. The duration of the interbody period was 6–8 days shorter than in the control group. The introduction of an additional dose of energy feed into the diet reduced the service period by 10–12 days, the frequency of inseminations by 0.3–0.5, and an increase in calf yield by 2–3%.

Published: February 2021

The structure of the cultivated areas serves as the basis for the system of crop rotation, the main link in modern farming systems. The structure of sown areas and the system of crop rotations as the fundamental links of the farming system have close direct correlations and feed-backs with all other links of the farming system. On the one hand, they are fundamental, first of all, for organizing the soil protection and nature conservation of the territory, since in each farm the sown areas of agricultural crops on arable land prevail over the area of other agricultural lands. On the other hand, the system of crop rotation, which is developed on the basis of the promising structure of sown areas, is the basis for other links of the farming system. For more efficient use of arable land, increasing the yield of major agricultural crops, meeting the needs of farms with crop production, improving soil fertility, it is necessary to change the structure of sown areas taking into account the specific agro-climatic conditions of the steppe zone. There are two subzones in the considered zone: arid and moderately arid one. We have substantiated and optimized the structure of cultivated areas in order to increase soil fertility, ecological balance and productivity of agricultural landscapes for these two sub-zones of the steppe zone. For the arid sub-zone, in the structure of sown areas, winter and spring crops should occupy 51.7%, legumes – 9.8%, fodder – 12.5%, industrial – 21%, vegetables – 5%. For the moderately arid sub-zone in the structure of sown areas, winter and spring crops should occupy 42.0%, legumes – 10.3%, corn for grain – 13.7%, fodder – 10.5%, industrial – 17.0%, vegetables – 5%, potatoes – 1.5%.

Published: February 2021

The article discusses the results of studying the effectiveness of using new generation herbicides: both applied before the emergence of corn seedlings ("Merlin" (150 g/ha); "Cassius" (50 g/ha)), and by seedlings ("Elumis" (1.0–2.0 l/ha)) – on crops of three maize hybrids. The studies were carried out in 2017–2019. The objects of research were maize hybrids of various early ripening (originator Kabardino-Balkaria Research Institute of Agriculture) – Kabardinskaya 3812 (late ripening), Camilla SV (mid-late), and white grain food corn Bella 451 (cultivated not only for obtaining varietal seeds, fodder, but also to meet the food needs of the indigenous population). Flour and cereals from white grain corn are used in most ethnic cuisines of the North Caucasus. In this regard, it is very important to put into production, along with the yellow grain forms used for fodder, highly productive varieties and hybrids of white grain corn for food purposes. The variety is medium late and food grade. The purpose of the research was to establish the level of harmfulness of weeds and their death rate at different periods of their introduction, as well as to determine their effect on the growth, development and yield of corn grain. The scientific novelty lies in the fact that in the conditions of the foothill zone of the Republic of North OssetiaAlania, studies have been carried out to establish the optimal terms and methods of applying herbicides in the fight against weeds when cultivating new highly productive corn hybrids. As a result of the studies, it was found that the treatment of the soil with the herbicide "Elumis" was more effective in comparison with the control option. At the same time, the grain yield was: for the Kabardinskaya 3812 hybrid 8.7 t/ha – on an unfertilized background, 12 t/ha – on a fertilized one; for the hybrid Camilla SV – 8.5 t/ha on an unfertilized background, 11.7 t/ha – on a fertilized one; the Bella 451 hybrid has 7.0 t/ha – on an unfertilized background, – 9.9 t/ha – on a fertilized one. The responsiveness of the Kabardinskaya 3812 hybrid to the application of herbicides was more effective than that of other studied hybrids.

Resistance to lodging is one of the important factors in increasing manufacturability, which is one of the priority tasks for breeding peas. In connection with the morphotypes variety expansion, studies aimed at determining their resistance to lodging and the influence of various factors on it are relevant. The research was carried out in the conditions of the Krasnoyarsk forest-steppe, in the breeding nursery of the initial material. The article presents the results of a three-year study (2017–2019) of the following morphotypes: lamellar, with a baleen type of leaf, chameleons, with dissected leaflets, multiple odd-pinnate, lupinoids. Three samples of each morphotype were analyzed for the study. The aim of the work was to determine the proportion of various factors’ influence on the lodging of peas. The objectives of the study included calculating the lodging coefficients for each morphotype and identifying the effect on lodging of the following parameters: weight of seeds per plant, length of plants, weight of green mass during the flowering period, the number of unproductive nodes. In the course of the lodging coefficients analysis, it was found that the samples of the chameleon morphotype and the samples with the baleen type of leaf were less lodged, with a coefficient of 0.7. The lamellar and multiply odd-pinnate specimens became the most lodged: their lodging coefficient was 0.5. For all morphotypes, a strong relationship was found between the score for lodging resistance and the lodging coefficient. The lodging of all samples in the total sample was more influenced by the weight of seeds per plant (64.7%) and the weight of green mass in bloom (35.3%). When analyzing each of the morphotypes from the studied parameters, the weight of green mass prevailed in the effect on the lodging of samples of dissected leafy (88.4%), multiple-pinnate (41.3%) and mustachioed (83.7%) morphotypes. The weight of seeds from plants had a greater effect on lodging of samples of lupinoid (50.0%) and lamellar (36.8%) morphotypes; the length of plants was relevant for chameleons (32.4%) and leafy (36.8%) specimens, and the number of unproductive nodes was relevant for chameleons (32.4%).

The great attention that is now being paid to triticale by breeders is due to the hopes of combining in one organism all the valuable that wheat and rye can give. The study of morphological characters using the most typical samples of triticale, characterizing the ecologicalgeographic and genotypic diversity of this synthetic genus, allows us to reveal the patterns of their variability for use in breeding programs and in taxonomy. As a result of studying 36 samples of triticale of various origins and ploidy different levels in terms of plant height and resistance to lodging, it was found that there is a very close correlation between these two parameters. Spring and winter forms significantly differ from each other in terms of plant height. Spring forms are lower than winter ones. The largest number of spring triticale samples have plant height from 110 to 130 cm, and hexaploids – from 130 to 150 cm. The majority of hexaploid triticale spring forms were obtained in Mexico and Russia. Mexican triticale plants are much lower in height than Russian ones. A close correlation was established between the resistance to lodging of triticale plants and the length of the stem. As a rule, specimens with heights not higher than 115 cm are characterized by high resistance to lodging. The amplitude of variability in plant height in triticale is quite significant at all ploidy levels. The range of variation in plant height is greatest at the hexaploid level – from 50 to 200 cm. In tetraploids it ranges from 70 to 160 cm, in octoploids – from 80 to 170 cm. The highest average value of plant height in octoploid forms of triticale is 133.8 cm, in tetraploids – 122.7 cm, and the smallest in hexaploids – 114.5 cm. This is explained by intensive selection work carried out at this level of ploidy.

Published: February 2021

The article presents the results of studies of the thermal fatigue strength of diesel cylinder heads and their resource under operating conditions, by using the most advanced technology for their restoration. Based on the results of theoretical calculations of durability and operational studies, a restoration technology has been proposed, which makes it possible to increase the resource of cylinder heads by 2 ÷ 2.5 times. For this purpose, the non-uniformity of the temperature field on the firing bottom of the cylinder heads of YaMZ-238NB diesel engines was theoretically determined and experimentally confirmed. On the basis of theoretical calculations, the most heatstressed sections of the plane of the cylinder heads of diesel engines bonded to the cylinder block were determined, and the appearance of cracks in them. When developing a method for calculating the temperature fields of the fire bottom, the universal finite element method (FEM) was used. This method makes it possible to take into account the geometry and conditions of thermal loading of the cylinder heads quite accurately. For the determination of temperature fields, a well-founded assignment of the boundary conditions is crucial. With this in mind, a number of surfaces were determined that characterize the durability of the entire part during operation. As a result of calculations carried out on a computer, temperature fields have been obtained that make it possible to analyze the distribution of temperatures and temperature gradients at any point of the fire bottom. The highest temperatures (620...635K) are localized in the central part of the fire bottom, which is two times higher in thermal intensity than the peripheral one and confirms the appearance of cracks in these places during the operation of diesel cylinder heads.

Published: February 2021

Among perennial leguminous grasses, the leading place is occupied by alfalfa, which has valuable biological characteristics and economically useful traits, which have great potential and prospects for use. Alfalfa is grown in more than 80 countries of the world on an area of over 35 million hectares, in various climatic and ecological conditions and on a variety of soils. Alfalfa increases soil fertility as a result of nitrogen accumulation. Alfalfa provides high-protein feed, carbohydrates, mineral salts, including trace elements, in terms of nutrient content. Alfalfa, like other perennial legumes, is used for hay, grass flour, and green mass. Alfalfa contains a lot of lysine, and in terms of the content of essential amino acids, it surpasses corn, sorghum, soybeans, barley and a number of other crops. In recent years, the acreage of alfalfa has been expanding, the demand for seeds is increasing, but their production remains at a low level. The aim of the study is to study various varieties of alfalfa, in order to create varieties that are resistant to biotic and abiotic to stress environmental factors for cultivation in the North Caucasus. According to research, it was established that Sinegibridnaya and Kizlyarskaya alfalfa varieties surpassed other varieties by 4-6% in terms of height and green mass. The higher productivity among the tested alfalfa varieties was possessed by the Kizlyarskaya variety, in which the yield indicators were most successfully combined with height and green mass.

The aim of the research is to study the method of vegetative propagation by cuttings to obtain a viable planting material of sawara cypress with a closed root system in the conditions of the Orel region. The study was carried out in 2019 at the private farm by Bykov L.S., Trosnyansky district, Orel region, in a cold closed ground, represented by gray forest medium loamy soils. Reproduction of the introduced species was carried out by rooting lignified cuttings in a nutrient substrate, which was prepared on the basis of neutralized peat with an acidity of 5.0 to 6.0 pH with the addition of perlite in a ratio of 4 to 1. Cuttings for the first group were cut on April 15 (before the beginning of the growing season), and for the second – on 16 May 2019 (after the beginning of the growing season) early in the morning from one mother plant, when the shoots are maximally saturated with moisture. Then the cuttings were planted in cassettes of 160 cells with an area of 0.24 m2 /piece to a depth of 2-3 cm and placed in an unheated protected ground with periodic watering. The best result for cuttings in the control group, harvested in mid-April (before the beginning of the growing season) – 96%, and for cuttings cut in mid-May (after the beginning of the growing season) – 60%. The mass of roots in established spring cuttings does not depend on the timing of reproduction, both variants showed an average weight of one root – 1.1 g. The profitability of the production of sawara cypress seedlings in the control group (when harvesting cuttings before vegetation) is 75%, which is 20% more than in seedlings grown from cuttings harvested after the beginning of the growing season.

Published: February 2021

The article presents the results of studies obtained through a comparative assessment of the infusion therapy effectiveness in treating dogs with parvovirus gastroenteritis. The problem of veterinary services for dogs in the conditions of Russian cities is becoming relevant, since in recent years in a number of cities of the Russian Federation outbreaks of natural focal and especially dangerous infections have been noted, when the source of their pathogens were domestic and synanthropic animals living near human dwellings, in economic and industrial objects and directly in urban areas. In connection with the increase in the incidence of parvovirus enteritis in dogs, the damage caused to them, in our country and abroad, the problem of studying this disease is becoming very urgent, as evidenced by numerous literary publications. The use of new drugs with a number of positive properties is limited and the issues of their use in veterinarian practice have not been sufficiently studied. The aim of the research was to carry out a comparative analysis of infusion therapy effectiveness when treating dogs with parvovirus enteritis. The studies were carried out at the “Doktor Aibolit” clinic in Rostov-on-Don. The subjects of the research were dogs with parvovirus enteritis. The initial diagnosis was made on the basis of anamnestic and clinical data, the final diagnosis was made only after laboratory tests and serological diagnostics. According to the principle of analogs, 15 dogs with parvovirus enteritis were selected for the experiment, and 3 groups were formed - 2 experimental and 1 control, 5 dogs each. Treatment of dogs with parvovirus enteritis was carried out in combination with the obligatory prescription of etiotropic and pathogenetic therapy. In 1 experimental group, Reamberin was used 100-200 ml once a day, in group 2 - RingerLocke’s solution; and in animals of the control group we used isotonic sodium chloride solution 0.9%. The effectiveness of infusion therapy in curing dogs with parvovirus gastroenteritis, using Reamberin, showed a 100% result; using a Ringer-Locke solution - 80%; using 0.9% sodium chloride - 60%. Based on the studies carried out, we recommend to use Reamberin at a dose of 100- 200 ml for intravenous infusion once a day for 4-5 days, for the treatment of dogs with parvovirus enteritis, as part of complex therapy.

The main factors constraining the development of animal husbandry is a weak fodder base, due to insufficient supply of nutrients; the costs of its production increase and becomes the cause of metabolic disorders in animals. The aim of our research was to study the embryotoxic and teratogenic effect of the new CVMC “Lizunets-Solevit” on white rats. For this reason, the drug was administered to pregnant females in the form of an aqueous suspension in different doses for 19 days. By the end of the study, no visible signs of fetal abnormalities were found after autopsy of the experimental rats. There was no significant increase in the number of corpus luteum compared with the control group at 1/10 dose by 1.1% and 1/20 dose by 1.95%, respectively. The preimplantation death of zygotes was taken into account on the embryotoxic effect of the drug, in comparison with the control group at a dose of 1/10 more by 19.7%, and at a dose of 1/20 less by 6.23%. The total embryonic mortality is higher in the experimental groups of animals by 12.69% and 3.74% than in the control. Post-implantation death of embryos in the control group was 4.99%, in the experimental 1/10 dose - 4.69% and in the experimental 1/20 dose - 6.66%. In terms of physiological development, the rat pups of the experimental groups did not differ from the control. Thus, it was found that CVMC “Lizunets-Solevit”, in doses of 1/10 and 1/20, has no embryotoxic and teratogenic effects in the body of white rats, their embryos and young animals of the neonatal and postnatal periods of life.

The number of T-lymphocytes in the subacute course decreases to 28.9±1.4% and in the chronic course it increased to 69.1±1.2%. However, against the background of lymphopenia, the absolute value of lymphocytes also decreased to 0.70±0.038·109 /l in the acute form of the disease. In chronic pneumonia, the number of lymphocytes was at the level of 0.44±0.04·109 /l. The T-x/T-c ratio also changed, depending on the form of enzootic pneumonia. With subacute – 1.7, and with chronic – 2.28. The entrikim treatment of piglets with a subacute course carried out for 7 days and a blood test 5 days after the implementation of sanitation showed that the number of Tlymphocytes increased twofold to 1.40±0.04·109 /l, while the Tx/Tc ratio was 2, 28, which corresponds to the physiological norm. After the treatment of piglets with a chronic course, all analyzed parameters characterizing the state of T-cell immunity testified to its normal functioning. A decrease in the total number of T-lymphocytes, individual EAK populations, indicate a depressive state of lymphopoiesis. A decrease in the number of T-lymphocytes to 0.44±0.04·109 /l in chronic course up to indicates a deep suppression of cellular immunity. In the subacute form of the disease, the number of B-lymphocytes decreased to 14.07±1.92%, but increased to 32.64±0.3% in the chronic course. But against the background of lymphopenia in subacute form, the absolute value of lymphocytes decreased to 0.36±0.04·109 /l, and in chronic lymphopenia to 0.20±0.06·109 /l. In the subacute form of the disease, the content of Ig A (1.49±0.03 mg/ml) and Ig G (1.39±0.02 mg/ml) does not differ from healthy animals, but a low level of Ig M (11.0±0.12 mg/ml) indicates a negative effect of mycoplasmas on humoral immunity. In chronic course, there is a sharp decrease (by 30%) Ig A to 1.49±0.03 and vice versa, a sharp increase by 30% in the Ig G content (11.8±011 mg/ml). After treatment of piglets with a subacute course of the disease, the number of B-lymphocytes increased by 2 times, and after treatment with m with a chronic course of the disease, by 3.5 times to 0.70±0.04·109 /L. The use of entrikim has a positive effect on humoral immunity, as the amount of Ig G increases by 45%. The therapeutic efficacy of entrikim increases due to the synergistic interaction of enrofloxacin, trimethoprim and tilmicosin phosphate. The therapeutic efficacy of entrikim in the subacute course was 90.7%, and in the chronic one – 74.4%.
TERENY ZIELONE W ZABYTKOWYM KRAJOBRAZIE KRAKOWSKIEGO KAZIMIERZA
Authors: Malec Tomasz
Published: February 2021

W krajobrazie polskich miast coraz rzadziej spotykamy nie tylko zieleń wysoką, ale tereny zielone w ogóle. Zauważyć należy, iż rola terenów zielonych, szczególnie w miastach jest złożona; stanowią one nie tylko miejsca rekreacji i wypoczynku, ale też przyczyniają się do zmniejszenia poziomu zanieczyszczenia powietrza oraz poprawy kondycji psychofizycznej człowieka. Dzięki swoim naturalnym walorom zieleń miejska stanowi też znaczący element estetyki krajobrazu zurbanizowanego. Ponadto, co bardzo istotne w aktualnych warunkach niskiego poziomu zaufania publicznego, tereny zielone sprzyjają integracji i budowie więzi o charakterze społecznym. Krakowski Kazimierz stanowi przykład gęsto zabudowanej dzielnicy miejskiej o charakterze historycznym, posiadającym niewielką ilość terenów zielonych. Efektem tego jest zmniejszenie stopnia atrakcyjności dzielnicy nie tylko dla mieszkańców, ale też potencjalnych nabywców nieruchomości oraz turystów. Zabytkowy charakter dzielnicy wymaga szczególnie uważnego, uwarunkowanego rodzajem zabudowy, podejścia do problematyki restauracji oraz zakładania nowych terenów zielonych. Bulwar Inflancki, jeden dwóch znaczących obecnie w skali dzielnicy terenów zielonych jest obszarem, stanowiącym przedmiot starań o zabudowę potencjalnych inwestorów. Wynika z tego, iż poziom świadomości, dotyczący roli terenów zielonych w tkance miejskiej pozostaje na relatywnie niskim poziomie również wśród osób zajmujących się szeroko pojętym budownictwem. Oznacza to, iż niezwykle ważna staje się popularyzacja wiedzy o korzyściach płynących z utrzymywania terenów zielonych. Celem artykułu jest zarówno przedstawienie argumentów przemawiających za utrzymaniem istniejących drzew, jak i znalezienie możliwych rozwiązań, zwiększających udział terenów zielonych Kazimierza przy uwzględnieniu aspektów kulturowych.

Az Innovációs és Technológiai Minisztérium (ITM) 2020. év elején közzétette az elfogadott energia- és klímapolitikai stratégiai dokumentumokat, amelyek meghatározzák Magyarország rövid- és hosszútávú energiastratégiáját. A stratégia alapvető célkitűzései megfelelnek az Európai Tanács 2019. december 12-i következtetéseiben foglaltakkal, miszerint fokozni kell a globális éghajlat-politikai fellépést. Magyarország Kormánya a megfogalmazott akciótervekkel igyekszik megvalósítani azt a célkitűzést, hogy az Európai Unió és a világ többi vezető gazdasági hatalma, a Párizsi Megállapodásban kitűzött célokkal összhangban, legkésőbb 2050-re klímasemlegessé váljon. Ez a vállalás fogja meghatározni a magyarországi energiaszektor, és a legnagyobb energiaszükségletű iparágak elkövetkező évtizedeit. Cikkemben bemutatom az eddigi energetikai trendek és mutatók alakulását, hogy mélyebb betekintést nyerjen az olvasó a szintén elemezni kívánt hat, úgynevezett „zászlóshajó-projektek”-be, amelyek az ITM által beazonosításra kerültek és a legfontosabb beavatkozási területeket fedik le.

MORPHOLOGICAL AND BIOINFORMATICS STUDY FOR RADIX AURICULARIA SNAILS IN FRESHWATER IN BASRAH PROVINCE, IRAQ
Authors: Al-Asadi S. A. M.
Published: February 2021

Radix auricularia (Lymnaea auricularia) snails are the main intermediate host of Fasciola gigantica in the middle and South of Iraq. Recently, some studies suggest these snails are not present in Iraq, in particular Basrah province. Thus, the current study was aimed to use the bioinformatics analysis in the determination of Radix sp. in Basrah and also aimed to identify morphological characteristics of this species in the AL-Sewaib river, Basrah. Four hundred R. auricularia snails were collected from the AL-Sewaib river during May 2018 to March 2019. The results of the bioinformatics analysis showed according to the mitochondrial cytochrome c oxidase subunit I, the presence of R. auricularia snails in Basrah province and these snails are more closely related to Iranian R. auricularia snails than those for European counties and Russia. This study also displayed the existence of the polymorphism phenomenon in R. auricularia snails collected from the AL-Sewaib river which there were six different forms (A, B, C, D, E and F). These forms had variations in the colour and form of shells along with a variation in the number of eggs (30-56) per an egg mass. In addition to this, these R. auricularia forms had variations in their distributions. Form E had the highest spread percentage (33%) followed by 17, 15, 14, 11 and 10% for forms B, D, C, A and F, respectively. These forms had also variations in their morphological characteristics. The largest form was the form D whereas the smallest form was the form B but other forms A, C, E and F were similar and had moderate sizes.Thus, the current study concludes the existence of R. auricularaia snails in Basrah as a representative city for the southern part of Iraq and also confirmed the presence of the polymorphism phenomenon in the members of R. auricularaia obtained from the AL-Sewaib river.

Authors: & Mohammed-Ridha Mohammed
Published: February 2021

This study was aimed to investigate the response surface methodology (RSM) to evaluate the effects of various experimental conditions on the removal of levofloxacin (LVX) from the aqueous solution by means of electrocoagulation (EC) technique with stainless steel electrodes. The EC process was achieved successfully with the efficiency of LVX removal of 90%. The results obtained from the regression analysis, showed that the data of experiential are better fitted to the polynomial model of second-order with the predicted correlation coefficient (pred. R2) of 0.723, adjusted correlation coefficient (Adj. R2) of 0.907 and correlation coefficient values (R2) of 0.952. This shows that the predicted models and experimental values are in good agreement. The results of the kinetic study showed that the second-order kinetic model was in good agreement with the experimental results and suggested that the mechanism of chemisorption controlled the LVX adsorption. The experimental results indicated that the adsorption of LVX on iron hydroxide flocs follows Sips isotherm with the value of the correlation coefficient (R2) of 0.937. Sips isotherm shows that both homogenous and heterogeneous adsorption can occur.
