abstract: Abstract The application of semiconductor photocatalysts in wastewater treatment has received increasingly attentions because of its potential utilization of solar energy. In this study, a novel visible light driven (VLD) BiOCOOH/g C3N4 composite photocatalyst was successful synthesized by a facile hydrothermal method. Afterwards, physicochemical properties of the resulting samples were investigated through X ray diffraction (XRD) scanning electron microscope (SEM) transmission electron microscopy (TEM) X ray photoelectron spectroscopy (XPS) Brunauer Emmett Teller (BET) surface areas, UV visible diffuse reflectance spectroscopy (UV vis DRS) transient photocurrent density, Mott Schottky (M S) and electrochemical impedance spectroscopy (EIS) measurement. Furthermore, the visible light photocatalytic (PC) performance was evaluated through the degradation of amido black 10B dye. All results indicated that the combination of g C3N4 and BiOCOOH could exhibited greatly visible light absorbance and photo generated charge separation efficiency, thereby resulting in the enhanced PC performance of BiOCOOH/g C3N4 composite photocatalyst. The optimal Bi/C molar rate in BiOCOOH/g C3N4 composite was determined to be 1/1, and the corresponding photodegradation rate for amido black 10B was 0.01794 min 1, which was nearly 2.19 and 5.73 folds higher than that of pure g C3N4 and BiOCOOH. The possible mechanism of the PC reaction was also discussed in detail. Furthermore, BiOCOOH/g C3N4 composite photocatalyst performed good reusability and stability even after four recycle utilization.

abstract: Abstract The sorption of amido black dye in water on iron composite nano material is defined in batch process optimizing starting amido black amount, agitation time, pH, nano martial dose, and temp. The sorption results complied with Langmuir, Freundlich, Temkin and Dubinin Radushkevich facsimilia. The proposed iron composite nano material were suitable for the sorption of amido black in water with determined 88% The uptake was impulsive and exothermic. The adjusted batch limits were initial concentration 100 mg/L; agitation time 25 min, pH 7.0, dose 1.0 g/L and 25 degC temperature. The thermodynamic parameters like DGdeg, DHdeg and DSdeg were 8.14, 8.10 and 8.02 kJ/mol at 20, 25 and 30 degC temps; 4.32 kJ/mol and 9.30 x 10 3 kJ/mol K. The pseudo first order and liquid film diffusion mechanistic of the sorption were projected. The proposed sorption process was quick, ecological responsive and low priced as may be utilized in normal water conditions. The artificial neural network modelling confirmed the applicability of the developed method. The method was competent to grind at normal water assets pHs with low sorbent amount and agitate time. The sorption process may be practical for the elimination of amido black dye from some water assets at large and low priced scale.

abstract: This article contains the experimental and statistical data related to decolourization of Amido Black 10B using photocatalytic process. Box Behnken experimental design (BBD) has been used to study the influence of operational parameters on photocatalytic oxidation of Amido Black 10B by using zinc oxide (ZnO) as a catalyst. This data set presents a concise description of experimental conditions for variable factors such as initial dye concentration of 100 ppm, oxidant dosage 20 mMol/L and catalyst dose 1g/L at natural pH for 4 hr of reaction time in presence of 12W intensity ultra violet radiation were optimized for over a response parameter, decolorization efficiency of Amido Black 10B. The effects of decolorization on process variables were investigated by developing a mathematical model, results indicated that ZnO can be used as an efficient catalyst for the decolorization of Amido Black 10B. Analysis of variance (ANOVA) showed a high coefficient of statistical measure value (R2 0.9915) and prediction of the driven regression model was found to be satisfactory.

abstract: The main object of this work is to remove Amido black 10B using a new type of bentonite based adsorbent with cationic groups by the modification of polyallyl amines between the interlayers of bentonite. Fourier transform infrared, X ray diffraction, thermogravimetric analysis, and scanning electron microscopy were used to characterize the functionalized bentonite. A series of batch adsorption experiments were performed. The maximum adsorption amount was 144.08 mg g 1 when the pH was 2 and the contact time was 120 min. In addition, the equilibrium isotherm data were analyzed using Langmuir and Freundlich isotherm models, while only the Langmuir model could provide a high correlation. Therefore, this study provided a new functionalized bentonite as a low cost adsorbent for dye removal from water.

abstract: Acid Black 10B (AB10B) is widely used for the production of textiles, leather and prints. It is a representative of azo dyes and it is well documented that some of these compounds are mutagenic per se, and that cleavage products (in particular aromatic amines) may cause damage of the genetic material and cancer. Since no toxicological data on AB10B have been published, we evaluated its mutagenic activity in Salmonella/microsome assays and studied its acute toxic and genotoxic properties in a human derived liver cell line (HepG2) which retained the activities of drug metabolizing enzymes. The compound did not cause cytotoxicity (MTT assay) but clear genotoxic effects were detected in pro and eukaryotic indicator cells. Dose dependent induction of his+ revertants was seen in strain TA98 which detects frameshift mutations without metabolic activation; a more pronounced effect was seen in its derivative YG1024 which overexpresses N acetyltransferase. Induction of single/double strand breaks by Comet assay was detected with concentrations 0.125 mg/mL in liver derived cells; as well as increased rates for micronucleus (reflecting structural and numeric chromosomal aberrations) and nuclear buds which are a consequence of gene amplifications were seen with a higher dose (2.0 mg/mL) (p 0.05; Tukey's test) The mutational pattern which was observed in the bacterial tests indicates that the cleavage product p nitroaniline may cause the genotoxic effects of the dye. Our findings indicate that exposure of humans and the release of the compound into the environment may lead to adverse effects due to its DNA damaging activity.

abstract: Titanium oxide nanoparticles were doped with copper and characterized by XRD, FT IR, TEM, and SEM. The surface morphology was spherical with 15 26 nm as particle size. The doped titanium oxide (Co/TiO2) nanomaterial was used for photodegradation of amido black dye in water. The maximum photodegradation of amido black obtained was 90% The values of free energy and enthalpy were negative, indicating spontaneous photodegradation of amido black dye. The photodegradation of amido black dye obeyed first order kinetic model. The photodegradation mechanism of amido black involved adsorption of the dye on the surface of cobalt doped titanium oxide and its degradation under UV radiation. The electron (e and hole (h+ pairs were generated by Co/TiO2, which consequently generated superoxide oxygen anion and hydroxyl free radical. These species degraded amido black dye. The reported method was fast, effective, and economic, which may be utilized to remove amido black in water. The doped TiO2 catalyst was quite stable and can be used up to 5 cycles.

abstract: The bacterium, Kocuria kristinae RC3 capable of decolorizing sulfonated azo dye, amido black 10B was isolated using enrichment technique and identified by 16s rRNA gene sequencing. A maximum decolorization of 74.19% was achieved in the mineral salt medium at 37 degC and 24 h of incubation time. Effect of medium components and process conditions on decolorization efficiency was studied using response surface methodology involving a central composite design. Further, the interactions between the process conditions, i.e. pH, temperature, cell mass, dye concentration, and medium components, i.e. glucose, yeast extract, K2HPO4 and (NH4)2SO4 concentration were modeled and investigated. The predicted values were found to be in good correlation with experimental values. The process conditions were optimized which resulted in 93.0% dye decolorization by the bacteria in 24 h. The optimized process conditions for maximum decolorization of amido black 10B by the bacterium were pH (7.4) cell mass (2.9 g/L) temperature (35.3 degC) and dye concentration (137.46 mg/L) in 24 h. The optimal medium conditions for maximum decolorization determined by RSM were glucose (3.17 g/L) yeast extract (1.05 g/L) K2HPO4 (1.66 g/L) and (NH4)2SO4 (1.06 g/L) Under these conditions, maximum decolorization of 96.83% was achieved in 24 h. The results demonstrated that K. kristinae RC3 could be employed for the treatment of amido black 10B contaminated wastewater/effluents.

abstract: Proteins separated by SDS polyacrylamide gel electrophoresis need to be stained with organic dyes to be visualized. Once stained the intensity of each stained protein band can be used to compare the differences in protein concentration and to measure the relative concentration of any protein band. The most popular standard protein staining is with Coomassie Blue R 250 which takes an hour to stain proteins to saturation and several hours to remove background staining. Direct Red 81 and Amido Black stain proteins within 2.5 min and staining is complete by 10 min. Here the rapid staining of proteins with Direct Red 81 and Amido Black in comparison to staining with Coomassie Blue R 250 is described.
