摘　　要：以钠基膨润土为原料,利用脱乙酰度90%、浓度为0.5%的壳聚糖溶液对其进行改性,制备了壳聚糖负载膨润土,并应用于含Cu2+模拟废水的处理。确定了最佳实验条件:负载土的投加量15 g/L、pH值为8、离心时间为10 min,在此条件下对Cu2+的去除率达到96.50%。并对负载土的吸附行为和性能进行了研究。Bentonite was modified by 0.5 % chitosan with 90% deacetylation degree , and a new chitosan coated bentonite was gained, then it was used to treat Cu2＋ wastewater. The best treatment conditions were determined as follows ： dosage of the chitosan coated bentonite 15 g/L, pH = 8, the centrifugal time 10 min,under above conditions,the removal rate of Cu2＋ can reach 96.50%.
