Abstract

The adsorption of platinum (IV) in hydrochloric acid solutions of a composite based on N,N-bis(3-triethoxysilylpropyl)thiourea and 4-vinylpyridine-2-hydroxy-ethylethacrylate copolymer is studied. The value of the static adsorption capacity of the composite for platinum(IV) is found to be 215 mg/g. To describe the nature of the adsorption, Langmuir, Freundlich, and Dubinin-Radushkevich models are used. The adsorption kinetics is estimated using Boyd-Adamson models of pseudo-first and pseudo-second order and the Elovich equation
