摘要
介绍了天然有机高分子化合物———甲壳素和壳聚糖的制备、化学结构和特性 ,阐述了其在水处理中的应用及发展前景。甲壳素和壳聚糖的来源广泛 ,其性能优良、无毒、无公害、可生物降解 ,可用作吸附剂、絮凝剂、分离膜材料、离子交换剂和杀菌剂 。
Preparation methods,chemical structures and charateristics of chitin and chitosan,natural organic polymer compounds,are presented.Their application and development prospects in water treatment are discussed.Chitin and Chitosan with abundant sources are characterized by excellent property,non toxicity,nuisance free and biodegratability.They can be used as adsorbing agents,flocculating agents,separating membrane materials,ion exchangers and bactericides.So they are a new kind of materials used in water treatment with brilliant prospects.
