摘要
以聚苯乙烯小白球树脂为原料,经硝化、还原、接枝等反应,合成了含有硫脲功能基的新型螯合树脂,研究了该树脂对Ag+离子的吸附性能。结果表明,在实验条件下,新树脂在含有Ag+、Cu2+、Zn2+、Fe3+等混合离子的体系中,对Ag+有良好的吸附容量和选择性,在一定条件下,能定量地解析树脂所吸附的Ag+。
A new thiourea chelating resin was synthesized by the process of nitrification, reduction, grafting reaction from polystyrene microsphere, and its absorption of Ag ＋ was studied. Result Showed that the resin has excellent absorption and selectivity for Ag ＋ in the coexist system of Ag ^＋ , Cu^2＋ , Zn^2＋ and Fe^3 ＋ .
