摘  要:
壳聚糖是自然界含量丰富的高分子有机物,改性后的壳聚糖被赋予更优异的理化性质,可广泛应用于土壤中的重金属吸附。介绍并对比目前常见的壳聚糖改性方式,分析巯基酯化壳聚糖对重金属吸附的机理,为巯基酯化壳聚糖在农业环境保护中的应用提供理论依据。

摘  要:
Chitosan is a macromolecule organic which is rich in nature,modified chitosan was endowed with more excellent physical and chemical properties;it is widely used in the adsorption of heavy metals in the soil.This article introduces usual chitosan modified methods and its comparison,analyzes the mechanism of sulfhydryl chitosan ester on heavy metal adsorption,provides theoretical basis for sulfhydryl chitosan ester's application in the protection of agricultural environment.
