摘要
壳聚糖是一种天然高分子,在其分子结构的重复单元中有—NH2和—OH,因而对金属离子有较好地吸附和配位能力。本文较全面地综述了壳聚糖及其衍生物对金属离子的吸附性能,简述了它们与金属离子形成配合物的结构及吸附机理,并对其发展前景作了展望。其中上篇主要讲述了壳聚糖及其衍生物对金属离子吸附性能的研究进展。
Chitosan is one of the most abundant natural polymers and widely distributed in the cuticle of the crustacea such as shrimps and crabs. This biopolymer has very useful functional groups such as hydroxyl, amine and acetamide groups, so it can interact with transition metal ions. This review is a closer look at the absorption abilities, the adsorption mechanism, and structural on metal ions of chitosan and its derivatives. Based on current research, some new and futuristic approaches are thoroughly discussed. In this part, the recent studies on chitosan and its derivatives were reviewed mainly on their absorption abilities for metal ions.
