摘要
杂环功能是一类对过渡金属离子、尤其是贵金属离子具有良好的吸附性能的功能基,它能利用环中的杂原子与金属离子形成稳定的多齿配合物,因此,含杂环功能基的螯合树脂,在分析、冶金、水处理、海洋资源利用等领域有广泛的应用价值[1-2]。目前文献报道较多的是将含硫、氮配位原子的杂环功能基直接键连在聚苯乙烯骨架上[3-7].
Two kinds of new chelating resins containing heterocyclic functional group(1-amino-5-methylthio-1,3,4-thia-dizole)were synthesized from macroporous chloromcthylated polystyrene.Their structures were characfierized by elemental analysis and infrared spectra.Their adsorption properties for Cu^2+,Pb^2+,Ni^2+,Zn^2+,Ag^+and Hg^2+had been studied.The results show that the newly synthesized resins have highly selective for Ag^+and Hg^2+and the resin has no affinity for Cu^2+.Pb^2+and Ni^2+.The introduction of hydrophihc polyvinyl alcohol spacer arm can increase the adsorption capacity and the length of spacer arm has effect on the adsorption capacities.
