Исследована адсорбция благородных металлов сополимером дивинилсульфида с 4-винилпиридином в растворах минеральных кислот. Показано, что исследуемый сополимер характеризуются высокими значениями статических сорбционных емкостей, которые для Au(III), Ag(I), Pt(IV) и Pd(II) достигают 1200, 340, 1040, 520 мг/г, соответственно. Проведено сравнительное исследование адсорбционных моделей Ленгмюра, Фрейндлиха и Дубинина - Радушкевича для описания экспериментальных изотерм адсорбции ионов благородных металлов на поверхности исследуемого сополимера. Определены константы и параметры рассмотренных моделей адсорбции. Анализ значений коэффициентов детерминации R2 свидетельствует, что адсорбцию ионов благородных металлов из сернокислых растворов и Ag из азотнокислых растворов наиболее адекватно описывает модель Ленгмюра. Полученные результаты указывают на то, что адсорбция ионов благородных металлов происходит на энергетически неоднородной поверхности и является мономолекулярным процессом. </p></abstract><trans-abstract xml:lang="en"><p>Organic polymers with N, S-functional groups are widely used as effective materials for the adsorption of transition metal ions. The adsorption of noble metals by copolymer of divinyl sulphide with 4-vinylpyridine has been studied in solutions of mineral acids. The copolymer under study has displayed high values of static sorption capacities, amounting to 1200, 340, 1040, 520 mg/g in Au (III), Ag (I), Pt (IV) and Pd (II), respectively. A comparative study of the Langmuir, Freundlich and Dubinin-Radushkevich adsorption models has been carried out to describe the experimental adsorption isotherms of noble metal ions on the surface of the copolymer under investigation. Constants and parameters of the considered adsorption models have been identified. Analysis of the values of the coefficients of determination R2 indicates that the adsorption of noble metal ions from sulphuric acid solutions and Ag from nitric acid solutions is most adequately described within the Langmuir model. The obtained results demonstrate that the adsorption of noble metal ions occurs on an energetically heterogeneous surface and represents a monomolecular process.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ионообменные смолы</kwd><kwd>сополимер дивинилсульфида и 4-винилпиридина</kwd><kwd>благородные металлы</kwd><kwd>модели адсорбции Ленгмюра</kwd><kwd>Фрейндлиха</kwd><kwd>Дубинина - Радушкевича</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ion exchange resins</kwd><kwd>copolymer of divinylsulphide and 4-vinylpyridine</kwd><kwd>noble metals</kwd><kwd>Langmuir</kwd><kwd>Freundlich</kwd><kwd>Dubinin-Radushkevich adsorption models</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Massey A.G., Thompson N.R., Johnson B.F.G.
