摘　　要：以氯甲基化聚苯乙烯为原料,合成了在聚苯乙烯基体和杂环功能基2-巯基苯并噻唑(MBZ)之间引入聚氧乙烯亲水性悬臂的新型螯合树脂,对所合成的树脂进行了元素分析、红外光谱和扫描电镜表征,对比研究了引入悬臂前后树脂对Hg2+等5种金属离子的静态吸附性能.实验结果表明:经过多步反应,引入亲水性悬臂之后,树脂的表面形貌没有变化,仍保留大孔结构,吸附选择性和功能基的利用率显著提高.Two kinds of new chelating resins containing hydrophlic spacer and hetrocyclic functional group （2- mercapto-benzothiazole） were synthesized were characterized by elemental analysis, from macroporous chloromethylated polystyrene. Their structures infrared spectra and scanning electron microscopy. Their adsorption properties for Cu^2 ＋ , Pb^2 ＋ , Ni^2 ＋ , Zn^2 ＋ , Ag^ ＋ , Hg^2 ＋ have been studied. The results show that the resins containing spacer arm have highly selective for Ag^ ＋ and Hg^2 ＋ , the resin has no affinity for Cu^2 ＋ ,Pb^2 ＋ and Ni^2 ＋, the introduction of hydrophilic polyethylene glycol spacer arm can increase the adsorption capacity and the length of spacer arm has dramatic effect on the adsorption capacities.
