| 摘 要： | 介绍了含吡啶基吸附材料对金属离子、无机阴离子及有机污染物的吸附分离研究进展。吡啶环的氮原子具有较强的配位功能,能与多种金属离子形成络合物。这类吸附材料对金属离子显示出高的吸附容量和吸附选择性,其吸附金属离子后形成金属主体高分子,然后再利用金属离子与具有配位性能的无机阴离子、有机污染物通过路易斯酸-碱在水溶液中进行配体交换,从而达到吸附分离的目的。作为高分子交换配体(PLE),这类新型吸附材料将是今后发展的重点。

| Abstract: | The research progress in adsorption separation of metal ions, inorganic anions and organic contaminants by using pyridine group-containing adsorbing materials is introduced. The N atom of pyridine ring has strong coordinate capacity and can react with many metal ions to form complexes. This type of adsorbing material shows high adsorption capacity and selectivity to metal ions. The formed metal host macromolecules through adsorbing metal ions can exchange the ligands with inorganic anions and organic contaminants possessing ligand performance in the Lewis acid-base aqueous solution to achieve the purpose of adsorption separation. This type of novel adsorbing material used as polymeric ligand exchanger （PLE） will be the developing emphasis in the future. |
