“…Synthesized silicon-organic polymer containing thiocarbamide group, which named poly[bis -N,N'-(3-silsesquioxanilpropyl)-thiocarbamide](PSTM-3T) was used in this work. There is report on preliminary study of Au(III) sorption thermodynamics on this sorbent [8], but sorption thermodynamics of Ag(I) and sorption kinetics of Au(III), Ag(I) have not detailed. This work focused on study of thermodynamics and kinetics of Au(III) and Ag(I) sorption onto PSTM-3T from aqueous solutions of nitric acid.…”

“…The separation of metal ions from solutions using sorbents has gained more attention due to their availability and costs. Sorption of precious metals (Au, Ag, Pt, Pd and Rh) on to silicon organic sorbents with groups of thiocarbamide, thioacetamide, aminosulfide and dioxothiocarbamide has been investigated [1][2][3][4][5][6][7]. Synthesized silicon-organic polymer containing thiocarbamide group, which named poly[bis -N,N'-(3-silsesquioxanilpropyl)-thiocarbamide](PSTM-3T) was used in this work.…”

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.

Abstract:The silicon organic polymer containing PSOT-3 (dioxothiocarbamide groups) has been synthesized and characterized, and the adsorption of Au(III) on PSOT-3 was investigated. The results showed that PSOT-3 had good adsorption capacity for Au(III), and the adsorption of Au(III) was found to be the most effective in 0.1~0.3 mol/dm 3 hydrochloric acid solution. The adsorption is physical and the process is endothermic, and Freundlich isotherm fits the data better than the Langmuir isotherm. The adsorption can be generally described by electrostatic interaction (Coulomb's force) between the adsorbent and the adsorbate. The high adsorption capacity of this sorbent has significant potential for gold recovery from aqueous solutions.
