摘　　要：壳聚糖是由甲壳素脱乙酰基而得来的一种天然线性高分子化合物。壳聚糖因具有耐碱、耐腐蚀、无毒、无味、易降解等特点,因而被应用于很多领域。该文综述了近年来壳聚糖及其衍生物作为吸附剂用于吸附重金属和非金属物质以及作为絮凝剂、抑菌剂和灭藻剂应用于各种水处理方面的研究进展。Chitosan is a kind of natural polymers. It is obtained by deacetylation of its parent polymer chitin. Because of its low price, alkali-resistant, corrosion-resistant, non-toxic, odorless and easily biodegradable characteristics, chitosan and its derivatives are widely used in many fields. In this paper, the application of chitosan and its derivatives as adsorbents, adsorbing heavy metals and non-metallic substances; as flocculants, antibacterial agents and algicide used in a variety of water treatment issues were summarized.
