摘要
In this paper,the sorption and exchange properties of Au(I)thiourea complex by NKC9 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=20,and the static saturated adsorption capacity of resin can reach 6438mg/gResin.The adsorbed Au(Tu)+2 can be qualitatively eluted with alcoholsulfuric acid solution,and the elution rate of gold is 985%.
