摘要
文章简介了汞离子作为一种有毒重金属在水中的危害,分析了壳聚糖作为一种生物吸附剂的结构、理化性质、改性机理和吸附机理;简要概述了以壳聚糖为基础的各种壳聚糖基吸附材料对水中有毒重金属汞离子的去除,并在此基础上简要分析了壳聚糖基吸附材料的优缺点。
The harm of mercury ion as a toxic heavy metal in water was briefly introduced. The structure, physicochemical properties, modification mechanism and adsorption mechanism of chitosan as a biological adsorbent were analyzed. The removal of toxic heavy metal mercury ions from water by various chitosan-based adsorbents was briefly summarized. On this basis, the advantages and disadvantages of chitosan-based adsorbents were briefly analyzed.
