摘　　要：介绍了壳聚糖的分子特点、絮凝机理以及在水处理方面的优势,重点综述了壳聚糖分子与硅酸盐矿石、纳米磁性材料的复合改性以及壳聚糖分子交联、接枝的官能团改性在水处理方面的综合研究进展,提出了未来的发展应结合我国水质的具体特点,寻找更高效、环保的壳聚糖改性水处理剂,并早日实现工业化发展。characteristic of chitosan molecule, flocculation mechanism and the advantage in water treatment were discussed. The compound modification of chitosan molecule, silicate mineral and magnetic nanomaterials as well as the com- prehensive research progress in water treatment refered to modification of crosslinked and grafted functional group was mainly reviewed. Eventually, it was pointed out that the future development of floeculants based on chitosan should be com- bined with the concrete characteristic of water in China. should be found in order to achieve industrialization. More efficient and eco-friendly flocculation with modified chitosan
