将两种四氮杂大环配体分别固载 (接枝 )到凝胶型和大孔型氯甲基化交联聚苯乙烯微球上 ,制备出四种高分子固载四氮杂大环配体 (分别以 A、A*、B、B*表示 ) ,研究了它们的结构以及与过渡金属 Cu2 + 、Co2 + 、Ni2 + 、Zn2 + 的配位作用、配位容量、配位选择性和洗脱再生性能 .结果表明它们对上述金属离子均有较好的配位能力 ,并可用稀盐酸洗脱金属离子 ,有一定的再生能力
Two kinds of tetraazamacrocyclic ligands were immobilized (grafted) onto the gel-type and macroporous chloromethylated crosslinked polystyrene microspheres respectively to prepare four kinds of macromolecule-supported tetra-aza (A, A *, B, B *, respectively). Their structures and their coordination with Cu2 +, Co2 +, Ni2 + and Zn2 + Properties and elution regeneration performance.The results show that they have a good coordination ability of the above-mentioned metal ions, and dilute hydrochloric acid can be used to elute metal ions, have a certain ability to regenerate
