Abstract: The functional group capacity of crosslinked macroporous polystyrene resin bearing 2-picolyl amine synthesized under optimum conditions is as high as 3.40 mmol/g resin.The influences of molar ratio of reagents, reaction temperature and reaction time on the nitrogen content of the resin were investigated.The sorption capacities of the resin for Au(Ⅲ), Ir(Ⅳ),Pt(Ⅳ),Pd(Ⅱ) and Rh (Ⅲ) are 768.0, 384.8, 356.0, 167.2, and 110.5 mg/g resin, respectively.The coordination ratio of AuCl4- ; IrClAuCl62-, PtClAuCl62-, PdClAuCl42-; and RHClAuCl63- are 1.15; 0.59, 0.54, 0.46 and 0.32, respectively.The distribution coefficients of the resin for Au(Ⅲ), Rh(Ⅱ) and Ir(Ⅳ) are 1.1×104, 2.6 ×103, and 1.9×103 mol/L, respectively.
