Abstract

In this investigation was used silicon-organic polymer containing thioacetamide group (-HN-C(S)-CH₃-), which named poly[N-(3-silseskquioxanilpropyl) thioacetamide]-(PTAS-3). PTAS-3 was produced from silicon-organic monomer: 3-triethoxysilylpropylamine by hydrolytic poly-condensation reaction. Sorption of Pt (IV) ions from aqueous solutions of hydrochloric acid has been studied using the silicon-organic polymer (PTAS-3) under different experimental conditions of concentrations of hydrochloric acid solutions, initial platinum concentration, time of contact, and temperature. Thermodynamic parameters were calculated based on Van´t Hoff equation. Experimental data were evaluated to find out kinetic characteristics.
