| 摘 要： | 壳聚糖分子存在大量游离的羟基和氨基,能与金属离子发生螯合作用,因此在金属离子吸附方面有着广阔的应用前景.综述了近年来冠醚、杯芳烃改性壳聚糖以及改性后的壳聚糖作金属离子吸附剂方面的研究进展,主要阐述了冠醚、杯芳烃通过醛基、烯丙基、卤代基、环氧基等基团与壳聚糖进行的接枝交联反应以及交联后的壳聚糖对多种金属离子的吸附情况.

| Abstract: | Chitosan has a lot of free hydroxyl and amino and can produce the chelation with metal ions,therefore,it has a broad application prospects in the aspect of metal ions adsorption.This paper reviewed the research progress of crown ether,calixarene modified chitosan and its adsorption properties of metal ions in recent years,described the crown ether and calixarene with chitosan cross-linking reaction through the aldehyde,allyl,halogenated base,epoxy and other groups,and mainly introduced their absorption effects of modified chitosan on metal ions. |
