摘要
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 。
Two tetraazamacrocyclics: 5,7,7,12,14,14 hexamethyl 1,4,8,11 tetraazacyclote tradecane (Me 6[14]N 4) and 5,7,7,12,14,14 hexamethyl 1,4,8,11 tetraazacyclotetradecane N acetic acid(Me 6[14]N 4CH 2COOH) were synthesized and attached covalently to chlormeth atedyl polystyrene bead both in gel and macropore type, respectively. The four polymer macrocyclic ligands(A,A *,B,B *) thus obtained showed a good coordination ability and their coordination capacities and selectivity properties towards Co(Ⅱ), Ni(Ⅱ), Cu(Ⅱ), and Zn(Ⅱ) were studied. The coordinated metal ion could be easily leached out by dilute hydro chloric acid from the polymeric macrocyclic ligands and the latter could be used repeatedly.
