摘　　要：O-羧甲基壳聚糖对六价铬具有吸附作用。本文研究了溶液的pH、吸附时间、温度和O-羧甲基壳聚糖的加入量对其吸附性能的影响。结果表明，在室温下，pH为2，吸附时间2h，O-羧甲基壳聚糖加入量为5g时，其吸附性能最好，吸附率可达98％以上。The adsorption exists between O-carboxymethyl chitosan and Cr（VI）. The effects of pH, adsorption time, dosage of O-carboxymethyl chitosan on its adsorption property were studied. The results showed that the adsorption property is the best and the absorption rate reaches 98% under the conditions of room temperature, pH 2, absorption time 2 h and dosage 5 g.
