摘　　要：壳聚糖是一种具有多种特性的天然高分子聚合物,以壳聚糖为原料制得交联壳聚糖及交联改性壳聚糖处理含重金属离子的废水,安全无毒、可生物降解、无二次污染。主要介绍了交联壳聚糖、化学修饰交联壳聚糖、分子印迹交联壳聚糖、磁性改性交联壳聚糖及多种技术联用的改性交联壳聚糖处理重金属废水的原理及应用,并对其发展前景进行了展望。Chitosan is a sort of natural polymers with a variety of characteristics. The cross-linked chitosan and cross-linking modification chitosan are made from chitosan, which are used to treating sewage with heavy metal ions due to their safe, non-poisonous, biodegradable and without secondary pollution features. It has been introduced that the principles and applications of disposing sewage containing heavy metal ions using cross-linked chitosan, chemically modified cross-linking chitosan, molecular imprinting cross-linking chitosan, magnetic modified cross-linking chitosan and the combination of the two or more technologies in cross-linking modification chitosan. In addition, the development potential of those kinds of materials and technologies were prospected.
