摘　　要：In this paper,the sorption and exchange properties of Au(I)thiourea complex by NKC9 macroporous strong acidic resin from wead acid solution have been investigated.The results show that the resin can effectively adsorb Au(Tu)+2 ions (Tu=thiourea) at pH=20,and the static saturated adsorption capacity of resin can reach 6438mg/gResin.The adsorbed Au(Tu)+2 can be qualitatively eluted with alcoholsulfuric acid solution,and the elution rate of gold is 985%.In this paper,the sorption and exchange properties of Au(I)thiourea complex by NKC9 macroporous strong acidic resin from wead acid solution have been investigated.The results show that the resin can effectively adsorb Au(Tu)+2 ions (Tu=thiourea) at pH=20,and the static saturated adsorption capacity of resin can reach 6438mg/gResin.The adsorbed Au(Tu)+2 can be qualitatively eluted with alcoholsulfuric acid solution,and the elution rate of gold is 985%.
