中文摘要：

壳聚糖分子中含有大量相邻的羟基和氨基,在合适条件下与过渡金属离子络合,能够得到具有特殊结构和性能的过渡金属配合物,因而在化学催化、吸附分离、自由基清除、材料等方面有广泛的应用。本文对壳聚糖过渡金属络合物的合成、结构表征、配位机理、热稳定性及其应用研究进行了综述,为壳聚糖过渡金属络合物的进一步发展提供科学帮助,并促进其规模化生产。

英文摘要：

Chitosan has a large number of reactive amine and hydroxy side groups,which can form transition metal complexes with special structure and property through chelation with transition metal ions under appropriate conditions,so that chitosan transition metal complexes have many important applications in the aspects of chemical catalysis,adsorption separation,free radical scavenging,material,etc.The synthesis method,structural characterization,chelating mechanism,thermal stability and application research of chitosan transition metal complexes were reviewed,in order to provide scientific help for its further development,and promote its large-scale production.
