| 摘 要： | 以聚苯乙烯树脂小白球为原料,经硝化、还原、接枝等反应,合成了含有硫脲功能基的新型PS-HQD螯合树脂,研究了该树脂对Au3+的吸附性能.结果表明,在实验条件下,新树脂在含有Au3+、Cu2+、Zn2+、Fe3+等离子的混合体系中,对Au3+有较高的吸附容量和良好选择性,在一定条件下,能定量地解吸树脂所吸附的Au3+.

| Abstract: | A new thiourea chelating resin was synthesized through the process of nitrification,reduction and grafting reaction on polystyrene microsphere.The adsorption property of the resin for Au3+ was studied.The results show that the resin has excellent adsorption and selectivity for Au3+ in the coexisting,system of Au3+,Cu2+,Zn2+and Fe3+,and Au3+could be desorbed quantitatively. |
