| Abstract: | The sorption and exchange properties of thiourea gold complex by D 072 macroporous strong acidic resin from 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 78.95?mg/g -resin . The Au(Tu) + 2adsorbed can be qualitatively eluted with alcohol-sulfuric acid solution,elution rate of gold is 96.5%. |
