文章研究壳聚糖对Pb^2＋的吸附特性，改变壳聚糖分子量、壳聚糖用量、吸附时间以及体系pH值等不同的吸附条件，考察壳聚糖对废水中Pb^2＋的去除效果。用分子量为1．23×10^5质量分数为1％的壳聚糖0．8mL，吸附时间为60min，pH值为5．5-6．5，温度为25℃时，对Pb^2＋浓度为100mg，L的Pb^2＋去除率可达99．5％。

A new product called ＂Chitosan＂ is used to removal lead（ II ） from wastewater. The effects of the molecular weight and dosage of Chistosan, pH, adsorption time and temperature in different condition had been studied. The results showed that if the molecular weight, mass fraction of Chitosan is 1.23 ×10^5 and 1%, when the dosage of Chitosan is 0.8 mL and the concentration of lead（ l] ） in wastewater is 100 mg/L,the optional pH range,time and temperature of adsorption is 5.5-6.5,60 min and 25℃ respectively and t...
