Thermodynamics and Kinetics of Au(III) and Ag(I) Sorption on to Silicon-Organic Polymer

Abstract

solid-liquid interface. Experimental data were evaluated to find out kinetic characteristics and found that the sorption of Au(III) followed pseudo-second order model and the sorption of Ag(I) followed pseudo-first order model. The sorption capacity increased with the increase in temperature and reached maximum value at 323 K and 328 K for Au(III) and Ag(I). The maximum sorption capacity of PSTM-3T for Au(III) and Ag(I) evaluated 333 and 129 mg/g.
