中文摘要:

研究了吸附条件对戊二醛交联硫代氨基脲树脂吸附金(Ⅲ)性能的影响。结果表明，在pH=2.0、吸附时间20 h、吸附温度25℃时，树脂对金(Ⅲ)的吸附率最高，为98.5%。光电子能谱表明，氮原子对树脂吸附金(Ⅲ)起主要作用，对铜(Ⅱ)、锌(Ⅱ)的吸附很少，对金(Ⅲ)的吸附选择性好。

英文摘要:

The adsorption conditions of a new chelating resin were discussed. The result shows the best condition: pH at 2.2, adsorption time at 20 hours and the adsorption temperature at 25℃, and the adsorption rate to Au(III) reached 98.5%. XPS showed nitrogen atom contributed to adsorption, the resin adsorbed small amount of copper and zinc, and good selective adsorption of gold.
