Ground-based observations within meter radio range are of importance for understanding processes occurring in the solar corona.

We present concepts, block diagram, and results of first observations of the Solar Spectropolarimeter of Meter Range (SSMD), launched for solar observations in the range 50–500 MHz in April 2016. The main purpose of this work was to develop an up-to-date digital radio spectropolarimeter able to record the full Stokes vector for sporadic solar phenomena taking place in the 50–500 MHz range.

We use a crossed log periodic antenna to detect solar radio emission. This antenna can simultaneously obtain horizontal and vertical polarization components. The main part of SSMD is a digital receiver based on an FX correlator architecture. We use the Fast Fourier Transform (FFT) algorithm based on the real-time pipeline circuit to construct amplitude dynamic spectra (intensity vs frequency and time).

SSMD has 4608 frequency channels with 97.66 kHz channel bandwidth and 97.66 kHz spacing. Time resolution is 1 s. The spectropolarimeter has a 50–500 MHz range. It can record the full Stokes vector. At present, SSMD observes two of four parameters in regular mode (I and V). We have observational data since 2016. The catalog development is in progress.

We plan to improve time and frequency characteristics, record all Stokes parameters, and conduct a calibration. We are working on providing access to the data archive via the Internet.
Heuristic model of solar X-ray spectrum according to satellite data for geophysical applications
Authors: Корсунская Юлия , Korsunskaja Yulia
Published: September 2019

Model and computational algorithm for recovering the X-ray component of the solar spectrum based on GOES XL (0.1–0.8 nm), XS (0.05–0.4 nm or 0.05–0.3 nm) and SDO QD (0.1–7 nm) channels data are presented. The model based the Mewe approximation of emission from optically thin plasmas that presents a temperature-like spectrum. The possibility to present the result spectrum as a superposition of Mewe spectrums placed in the solar absorbing atmosphere at one optical depth for its temperature parameter energy is suggested in this paper. So the model is a variation of the multi-temperature approximation. Spectrum parameters are determined on the basis of support functions, approximation expressions for which are given in appendix.

Using vertical sounding data obtained by the Irkutsk digisonde DPS-4 from 2003 to 2016, we have studied the frequency of occurrence of the F1 layer in winter conditions. The frequency of occurrence of the F1 layer in December–January is shown to be more than twice lower than that in February at any level of magnetic activity. At moderate and low solar activity under quiet geomagnetic conditions, the appearance of F1 layer in midlatitudes of the Northern Hemisphere may be caused by active thermodynamic processes, which lead to transformation or destruction of the circumpolar vortex at heights of the middle atmosphere. Such global dynamic changes occurring in the winter strato-mesosphere are often associated with sudden stratospheric warming events, which are accompanied by increased generation of atmospheric waves of various scales. These wave disturbances can propagate upward to the heights of the lower thermosphere and ionosphere, carrying a significant vertical flow of energy and causing variations in the composition, thermodynamic parameters of the neutral atmosphere and ionosphere.

Masalah pariwisata di Indonesia sekarang ini sangat memprihatinkan salah satunya terkait dengan menurunnya kepedulian dalam pengembangan objek wisata. Kuliah Kerja Nyata Universitas Ahmad Dahlan mengusung tema â€œPengelolaan Pariwisata sebagai Upaya Peningkatan Ekonomi Masyarakatâ€ yang tersebar di berbagai kabupaten di Jawa Tengah dan Daerah Istimewa Yogyakarta. Tema tersebut merupakan sikap taktis yang diambil UAD dalam menyikapi program pemerintah, yaitu Wonderful Indonesiaâ€”sebuah program kerja berbasis pariwisata. Setiap unit maupun divisi wajib membantu mendorong ekonomi masyarakat berbasis pariwisata melalui Program Kerja individu maupun bersama mereka. Untuk mencapai tujuan tema besar tersebut, beragam metode yang dilakukan, seperti berdiskusi dengan pengelola pariwisata, menulis jurnal pariwisata, pelatihan tourguide, dan pelatihan membuat video pariwisata. Melalui serangkaian metode tersebut, masyarakat secara signifikan dapat mempromosikan pariwisata melalui media sosial Blogspot, Facebook, Whatsapp, Intagram, dan sebagainya. Dampak nyata dari metode-metode tersebut adalah bertambahnya wisatawan lokal dan mancanegara yang berdatangan. Otomatis, tidak hanya masyarakat yang menjadikan pariwisata sebagai pekerjaan pokoknya yang mendapatkan keuntungan, namun pedagang, penganyam, dan peladang jagung pun mendapatkan keuntungan dari bertambahnya wisatawan lokal maupun mancanegara yang berdatangan setiap harinya.

Authors: Wiharto Wiharto , Fatimah Siti , Suryani Esti
Published: September 2019

Peningkatan kualitas kompetensi guru menjadi prioritas dalam rangka mewujudkan pendidikan yang bermutu dan profesional. Pemerintah mewajibkan guru yang hendak meningkatkan pangkat golongannya atau mendapatkan tunjangan sertifikasi dituntut untuk menulis artikel. Artikel yang dihasilkan diwajibkan untuk dipublikasikan. Untuk melaksanakan hal tersebut maka guru dituntut untuk menulis artikel, baik artikel yang berdasarkan ide/gagasan, artikel berdasarkan pengamatan/penelitian, maupun artikel berdasarkan literasi. Adanya kewajiban tersebut, kebanyakan guru yang hendak naik pangkat/golongan masih mengalami kesulitan untuk memulai menulis artikel. Hal ini dikarenakan oleh beberapa faktor, antara lain adalah ide yang sukar dikembangkan, pengolahan data yang rumit, ketidaktahuan penggunaan fasilitas teknologi informasi yang sudah ada dalam rangka mempermudah penulisan, dan faktor pribadi yang tidak mau berkembang. Sekolah SMA Negeri Karangdowo Kabupaten Klaten, sebagian besar sudah tersertifikasi. Sebagian dari mereka belum terlalu mahir dalam penggunaan teknologi informasi untuk membantu proses kenaikan pangkat atau perbaikan kualitas pembelajaran. Solusi dari permasalahan tersebut salah satunya adalah melalui program E-balada (Pembelajaran Dan Pendampingan dengan menggunakan teknologi informasi). Program E-balada merupakan program pendampingan penggunaan teknologi informasi seperti optimalisasi penggunaan tampilan menu pada microsoft word yang sudah ada, penggunaan zotero, schoology. Guru dapat memanfaatkan program ini sebagai alat bantu. Program E- balada ini dapat meningkatkan kualitas kompetensi mengajar maupun kualitas dari segi profesinya.

Teaching about childhood cancer to pupils aged 10–12 years: A randomised trial of two types of material
Authors: Nilsson Stefan , Hultman Jessica , Opperdoes Lina , Nolbris Margaretha Jenholt
Published: September 2019

The purpose of the study was to describe and compare pupils' experience of teaching about cancer, when a nurse used two different formats of teaching material to teach pupils aged from 10 to 12 years. Pupils from schools in Western Sweden were randomised to either Imaginary Friends or SEE-HEAR-DO pictures. A total of 197 of 231 pupils (85%) participated, and a majority knew someone who had had cancer before, and thought it was valuable to get knowledge about cancer. The Imaginary Friends intervention group felt happier/more content and calmer/more relaxed, and less tense/nervous after the education about cancer. The SEE-HEAR-DO group felt happier/more content after the education, and were to a significantly higher extent stimulated to ask questions. Both Imaginary Friends and SEE-HEAR-DO pictures can be used as teaching materials for pupils. The use of SEE-HEAR-DO pictures may increase the interaction between the school nurse and the pupils.

Nursing the feline patient following surgical management of idiopathic pericardial effusion by subtotal pericardiectomy
Authors: Osborne Lauren
Published: September 2019

A 4-year-old feline was admitted to the veterinary hospital for haemorrhagic pericardial effusion leading to cardiac tamponade of unknown origin. Concurrent subclinical hypertrophic cardiomyopathy (HCM) was also diagnosed. After significant diagnostic tests and reoccurrence of the effusion, the patient underwent a subtotal pericardiectomy. Results were consistent with neutrophillic/granulomatous pericarditis of unknown origin. This article discusses the nursing care implemented postoperatively, focusing on the major themes of pain management, pain scoring, management of the thoracostomy tube and the correction of dehydration and maintaining the patient's nutritional requirements. After 7 days of hospitalisation, the patient recovered well and was discharged.

Effects of physical activity on long-term survivorship after metal-on-metal hip resurfacing arthroplasty
Authors: Amstutz Harlan C. , Le Duff Michel J.
Published: September 2019

Aims

In previous studies, we identified multiple factors influencing the survivorship of hip resurfacing arthroplasties (HRAs), such as initial anatomical conditions and surgical technique. In addition, the University of California, Los Angeles (UCLA) activity score presents a ceiling effect, so a better quantification of activity is important to determine which activities may be advisable or detrimental to the recovered patient. We aimed to determine the effect of specific groups of sporting activities on the survivorship free of aseptic failure of a large series of HRA.

Patients and Methods

A total of 661 patients (806 hips) representing 77% of a consecutive series of patients treated with metal-on-metal hybrid HRA answered a survey to determine the types and amounts of sporting activities they regularly participated in. There were 462 male patients (70%) and 199 female patients (30%). Their mean age at the time of surgery was 51.9 years (14 to 78). Their mean body mass index (BMI) was 26.5 kg/m2(16.7 to 46.5). Activities were regrouped into 17 categories based on general analogies between these activities. Scores for typical frequency and duration of the sessions were used to quantify the patients’ overall time spent engaging in sporting activities. Impact and cycle scores were computed. Multivariable models were used.

Results

We found no association between any category of activity and a decrease in survivorship. Impact and hip cycle scores also failed to show any association with revision for aseptic failure or wear.

Conclusion

Return to sporting activities after surgery is safe for patients treated with well-designed and well-implanted HRA. Cite this article: Bone Joint J 2019;101-B:1186–1191
Is serial radiological evaluation of one-part proximal humeral fractures necessary?
Authors: Jacxsens Matthijs , Schmid Jeremias , Zdravkovic Vilijam , Jost Bernhard , Spross Christian
Published: September 2019

Aims

In order to determine whether and for whom serial radiological evaluation is necessary in one-part proximal humerus fractures, we set out to describe the clinical history and predictors of secondary displacement in patients sustaining these injuries.

Patients and Methods

Between January 2014 and April 2016, all patients with an isolated, nonoperatively treated one-part proximal humerus fracture were prospectively followed up. Clinical and radiological evaluation took place at less than two, six, 12, and 52 weeks. Fracture configuration, bone quality, and comminution were determined on the initial radiographs. Fracture healing, secondary displacement, and treatment changes were recorded during follow-up.

Results

In 100 patients (59 female, 41 male; mean age 57 years), 91 of the fractures (91%) remained stable. In five of nine patients (55%) with secondary displacement, surgery was recommended. Comminution, present in 23 patients (23%), was identified as a predictor of secondary displacement (p < 0.001). Patients’ age, sex, fracture configuration, and bone quality were not associated with secondary displacement (p ≥ 0.438). Nonoperative treatment resulted in a mean absolute Constant score (CS) of 80 (49 to 98), relative CS of 101% (63% to 138%), median subjective shoulder value of 95% (interquartile range (IQR) 90% to 100%), and median EuroQol five-dimensional questionnaire score of 0.89 (IQR 0.80 to 1.00) with bone union in all cases at one-year follow-up.

Conclusion

Radiological re-evaluation was only necessary in patients presenting with comminution and may be redundant for 77% of patients with one-part proximal humerus fractures. Nonoperative treatment of one-part proximal humerus fractures remains the mainstay of treatment with a low rate of secondary surgery, a high union rate, and good clinical results.

A randomized double-blind noninferiority trial, evaluating migration of a cemented vitamin E-stabilized highly crosslinked component compared with a standard polyethylene component in reverse hybrid total hip arthroplasty
Authors: Sköldenberg Olof G. , Rysinska Agata D. , Chammout Ghaz , Salemyr Mats , Mukka Sebastian S. , Bodén Henrik , Eisler Thomas
Published: September 2019

Aims

Radiostereometric analysis (RSA) studies of vitamin E-doped, highly crosslinked polyethylene (VEPE) liners show low head penetration rates in cementless acetabular components. There is, however, currently no data on cemented VEPE acetabular components in total hip arthroplasty (THA). The aim of this study was to evaluate the safety of a new cemented VEPE component, compared with a conventional polyethylene (PE) component regarding migration, head penetration, and clinical results.

Patients and Methods

We enrolled 42 patients (21 male, 21 female) with osteoarthritis and a mean age of 67 years (sd 5), in a double-blinded, noninferiority, randomized controlled trial. The subjects were randomized in a 1:1 ratio to receive a reverse hybrid THA with a cemented component of either argon-gas gamma-sterilized PE component (controls) or VEPE, with identical geometry. The primary endpoint was proximal implant migration of the component at two years postoperatively measured with RSA. Secondary endpoints included total migration of the component, penetration of the femoral head into the component, and patient-reported outcome measurements.

Results

In total, 19 control implants and 18 implants in the VEPE group were analyzed for the primary endpoint. We found a continuous proximal migration of the component in the VEPE group that was significantly higher with a difference at two years of a mean 0.21 mm (95% confidence interval (CI) 0.05 to 0.37; p = 0.013). The total migration was also significantly higher in the VEPE group, but femoral head penetration was lower. We found no difference in clinical outcomes between the groups.

Conclusion

At two years, this cemented VEPE component, although having a low head penetration and excellent clinical results, failed to meet noninferiority compared with the conventional implant by a proximal migration above the proposed safety threshold of RSA. The early proximal migration pattern of the VEPE component is a reason for continued monitoring, although a specific threshold for proximal migration and risk for later failure cannot be defined and needs further study.

Published: September 2019

Este artigo traz a educação superior como elemento chave para promover ação e mudanças. O enfoque é a formação de gestores partindo-se do pressuposto que as organizações e seus atores são essenciais para promover impactos positivos na sociedade. Neste contexto, este artigo se propõe a responder ao seguinte questionamento: De que maneira elementos contextuais, organizacionais e curriculares podem colaborar para a presença da temática Sustentabilidade na formação superior em Administração? Assim, o objetivo geral envolveu analisar em que medida elementos contextuais, organizacionais e curriculares colaboram para a formação superior em Administração sob a perspectiva da Sustentabilidade. Para tanto, foi realizado um estudo de caso de cunho qualitativo em uma Universidade privada do Rio Grande do Sul. A coleta de dados foi dividida em quatro etapas considerando: análise detalhada dos Planos de Ensino das disciplinas, realização de entrevistas junto a atores chave na gestão da instituição, grupo focal com estudantes, aplicação de questionário junto a estudantes dos últimos semestres do curso, e dados secundários presentes no site institucional e em documentos internos da instituição. Os principais resultados mostram que existe um movimento institucional que emerge principalmente da característica comunitária da Universidade e das avaliações externas. Existem práticas socioambientais, mas a IES é percebida mais sob a perspectiva da inovação e não da Sustentabilidade. O currículo da Administração sofreu mudanças que incluem a inserção de disciplinas específicas das áreas, o que vai ao encontro da demanda manifestada pelos estudantes.

Este estudo aborda os desafios da integração da pesquisa e ensino, a partir da extensão universitária, como uma estratégia importante para materializar a qualidade da formação acadêmica em Administração em direção aos objetivos do desenvolvimento sustentável (ODS). A ação de extensão, objeto de estudo, é desenvolvida pelo Departamento de Ciências Administrativas e Departamento de Administração Pública e Gestão Social da UFRN em colaboração com outros departamentos e campi da mesma instituição. O desenvolvimento da ação se deu na Associação da comunidade indígena dos Mendonça do Amarelão, no município de João Câmara/RN. Objetivou-se, a partir da ação de extensão desenvolvida, compreender como as situações-problemas são formuladas para parceira universidade-sociedade em busca do desenvolvimento sustentável via projetos de pesquisa, e como essas ações retroalimentam o sistema de ensino. A investigação ocorreu por meio da pesquisa-ação (THIOLLENT, 2003) e abordagem qualitativa na análise dos dados. A sistematização dos problemas e necessidades comuns (comunidade-universidade) levou a um tema central sob o qual foi construída a ação: a gestão de circuitos curtos de produção, com ênfase a alcançar a soberania e segurança alimentar e nutricional, promover a agricultura sustentável e assegurar padrões de produção e de consumo sustentáveis. Percebeu-se que a comunidade é orientada para a valorização, reconhecimento e preservação dos recursos locais, importante à efetivação dos ODS. Neste sentido, além da própria condição dos povos indígenas, como aquelas relacionadas ao território, há entraves locais relacionados à gestão da capacidade produtiva e organização da produção, burocráticos, comerciais e de gênero, que impactam na sua segurança e soberania alimentar e exigiram debate interdisciplinar, com vários campos do saber, e docentes envolvidos com as necessidades atuais da sociedade para alinhá-las ao ambiente de ensino e com questões de investigação na proposição de encaminhamentos necessárias ao desenvolvimento técnico-cientifico e cultural e à formação cidadã do graduando da UFRN, destacando a atividade de extensão como elo integrador entre a pesquisa e o ensino, e possibilitando a construção de uma proposta interdisciplinar unificada que reconhece a educação como uma prática emancipatória e contínua do ser humano.

What Matters in Population Health and How We Count It Among People With Intellectual and Developmental Disabilities
Authors: Havercamp Susan M. , Krahn Gloria L.
Published: September 2019

This issue, On Counting What Matters: Finding Adults With Intellectual and Developmental Disabilities in Population Health Data, presents an overview of health surveillance research for people with intellectual and developmental disabilities (IDD) in the United States. Although public health now conducts surveillance of people with disabilities broadly defined and compares their health status with that of individuals without disabilities, there are many challenges in conducting health surveillance of people with IDD. Difficulties include how to define cases, how to find cases, and how to obtain accurate information (Krahn, Fox, Campbell, Ramon, & Jesien, 2010). This issue will present critical conceptual and methodological issues, including recent prevalence and population health analyses, along with proposals that can lead to more equitable health and improved health surveillance for people with IDD.

BACKGROUND

We aimed to derive and externally validate a 0/2-h algorithm using the high-sensitivity cardiac troponin I (hs-cTnI)-Access assay.

METHODS

We enrolled patients presenting to the emergency department with symptoms suggestive of acute myocardial infarction (AMI) in 2 prospective diagnostic studies using central adjudication. Two independent cardiologists adjudicated the final diagnosis, including all available medical information including cardiac imaging. hs-cTnI-Access concentrations were measured at presentation and after 2 h in a blinded fashion.

RESULTS

AMI was the adjudicated final diagnosis in 164 of 1131 (14.5%) patients in the derivation cohort. Rule-out by the hs-cTnI-Access 0/2-h algorithm was defined as 0-h hs-cTnI-Access concentration <4 ng/L in patients with an onset of chest pain >3 h (direct rule-out) or a 0-h hs-cTnI-Access concentration <5 ng/L and an absolute change within 2 h <5 ng/L in all other patients. Derived thresholds for rule-in were a 0-h hs-cTnI-Access concentration ≥50 ng/L (direct rule-in) or an absolute change within 2 h ≥20 ng/L. In the derivation cohort, these cutoffs ruled out 55% of patients with a negative predictive value (NPV) of 99.8% (95% CI, 99.3–100) and sensitivity of 99.4% (95% CI, 96.5–99.9), and ruled in 30% of patients with a positive predictive value (PPV) of 73% (95% CI, 66.1–79). In the validation cohort, AMI was the adjudicated final diagnosis in 88 of 1280 (6.9%) patients. These cutoffs ruled out 77.9% of patients with an NPV of 99.8% (95% CI, 99.3–100) and sensitivity of 97.7% (95% CI, 92.0–99.7), and ruled in 5.8% of patients with a PPV of 77% (95% CI, 65.8–86) in the validation cohort.

CONCLUSIONS

Safety and efficacy of the l hs-cTnI-Access 0/2-h algorithm for triage toward rule-out or rule-in of AMI are very high.

BACKGROUND

Measurement of plasma adrenocorticotropic hormone (ACTH) is key in the differential diagnosis of hypothalamic-pituitary-adrenal disorders. Two-site sandwich immunoassays dominate clinical testing of ACTH in North America; however, discordant results between manufacturers have been repeatedly reported. To resolve the discrepancy, we developed a liquid chromatography–tandem mass spectrometry (LC-MS/MS) assay for the intended measurand, biologically active intact ACTH (iACTH).

METHODS

The multiple reaction monitoring LC-MS/MS assay was designed to selectively measure full-length iACTH, as well as ACTH analogs and fragments (i.e., ACTH1–24 and ACTH18–39). Epitope assignment of the Roche Elecsys antibodies was performed by MALDI-TOF mass spectrometry. A method comparison between Roche Elecsys and Siemens Immulite ACTH immunoassays was performed and clinically concordant/discordant results identified. In a subset of these samples, the iACTH concentration was determined using the LC-MS/MS method.

RESULTS

The lower limit of the measuring interval of the iACTH LC-MS/MS assay was 9 pg/mL (2 pmol/L). The assay was linear from 9 to 1938 pg/mL (2 to 427 pmol/L). Epitope mapping revealed that the Roche capture and detection antibodies bound residues 9–12 and 36–39 of ACTH, respectively. The iACTH LC-MS/MS analysis demonstrated that for discordant results between 2 immunoassays studied, only the Roche results were highly positively correlated with the iACTH concentration.

CONCLUSIONS

Immunoprecipitation of biologically active ACTH molecules followed by LC-MS/MS analysis enabled selective detection of iACTH and relevant biologically active fragments in plasma. Applied to the investigation of clinically discrepant results, this method can act as an arbiter of the concentration of iACTH present.
Detection of Colchicine using p-Sulfonated Calix[4]arene Modified Electrode
Authors: Pang Tao-Tao , Zhang Xu-Yan
Published: September 2019

Complex characteristics of p-sulfonated calix[4]arene (SC4A) and colchicine were examined using various techniques. Electrochemical impedance spectroscopy results enabled observation of the colchicine-SC4A interaction, and indicated that SC4A had high sensitivity to colchicine with a detection limit (S/N = 3) of 2 × 10-9 mol L-1. Cyclic voltammetry results indicated that the structural matching effect and the electrostatic interaction were the dominant stabilizing factors for the host-guest complexes
of colchicine and SC4A. Molecular mechanics simulation showed that the benzene ring of colchicine entered the SC4A cavity. The sensor enabled selective determination of colchicine even in the presence of common interferences. The results indicated that it was more difficult to oxidize the non-electrochemically active complexes. This study showed that p-sulfonated calix[4]arene can be used in the detoxification of colchicine poisoning and may be effective in the clinical treatment of colchicine poisoning in the future.

Published: September 2019

A new Schiff base [1-((2-(1H-indol-3-yl)ethylimino)methyl)naphthalene-2-ol] (HL) has been
synthesized by condensing (2-hydroxy-1-naphthaldehyde) with (2-(1H-indol-3-yl)ethylamine). In turn, its transition metal complexes were prepared having the general formula; [Pt(IV)Cl2(L)2], [Re(V)Cl2(L)2]Cl and [Pd(L)2], 2K[M(II)Cl2(L)2] where M(II) = Co, Ni, Cu] are reported. Ligand as well as metal complexes are characterized by spectroscopic techniques such as FT-IR, UV-visible, 13C & 1H NMR, mass, elemental analysis. The results suggested that the ligand behaves like a bidentate ligand for all the synthesized complexes. On the other hand, theoretical studies of the ligand as well its metal complexes were conducted at gas phase using HyperChem 8.0. These metal complexes exhibited good antibacterial activity.

Published: September 2019

A series of novel tris-trizole based neutral chemosensors (4a-c) have been synthesized via click reaction and characterized by various spectral techniques. All the synthesized triazoles were evaluated for their ion binding properties towards various cations (Cu2+, Zn2+, Ca2+, Co2+, Cd2+, Hg2+, Pb2+ and Ni2+) by UV-visible titration experiments. It was observed that the addition of Pb2+ ions to compound 4a led to significant changes in UV-visible spectrum and a new UV band was observed at 262 nm. Further, the Job′s plot confirmed the formation of 1:1 complex between compound 4a and Pb2+. The synthesized
chemosensor selectively sense Pb2+ ions in preference to other cations like Cu2+, Zn2+, Ca2+, Co2+, Cd2+, Hg2+, Pb2+ and Ni2+.

Published: September 2019

The adsorbent polymer/clay nanocomposites were prepared by in situ emulsion polymerization method. The prepared adsorbent was characterized using FT-IR, XRD, TGA and the surface morphology was analyzed using FE-SEM. The prepared polymer/clay nano-composite was used for the removal of malachite green and amido black 10B. The effects of initial pH, adsorbent dosage, initial metal ion concentration, contact time and thermodynamic studies on the malachite green and amido black 10B
adsorption were studied. The adsorption isotherm parameters of the adsorption process were determined by using Langmuir, Freundlich and Temkin adsorption isotherm equations. The kinetic parameters were predicted with Lagergren’s pseudo-first order and pseudo-second order equations. The effect of temperature of the adsorption process was demonstrated by using the thermodynamic parameters.
The maximum adsorption capacity of malachite green and amido black 10B onto polymer/clay nanocomposites was found at pH 7 and 2. Adsorption of malachite green and amido black 10B onto polymer/clay nanocomposites followed the Langmuir adsorption isotherm and it follows pseudo-second order rate constant equation The thermodynamic parameters, such as ΔHº, ΔSº and ΔGº were also determined which suggested that the studied adsorption process was an endothermic reaction.
