摘　　要：The adsorption behavior and mechanism of a novel thiol resin for Ag(Ⅰ) were investigated Experimental results showed that the statically saturated sorption capacity was 639 mg·g -1 resin at pH=4 5 in the HNO 3 NaAc medium Ag(Ⅰ) adsorbed on the thiol resin could be eluted with (5%～10%) (NH 2) 2CS-1 0mol·L -1 HCl and elution percentage was over 95% The resin could be regenerated and reused without apparent decrease of adsorption capacity The adsorption behavior obeyed the Freundlich isotherm The apparent adsorption rate constant was k 25℃ =1 56×10 -5 s -1 The enthalpy change Δ H of sorption was 40 2 kJ·mol -1 The functional group molar ratio to Ag(Ⅰ) was about 1∶1 and the mechanism of adsorption was examined by IR
