| 摘 要： | 从吸附温度、吸附剂投加量、pH值、反应时间、初始浓度等方面考察了自制壳聚糖磁性微球作为吸附剂对含铅废水的处理效果。结果表明：在初始pH值为5.0，反应时间为20 min，吸附剂的投加量为0.900 g，初始浓度为50 mg/L时吸附剂对Pb2+的吸附效果最佳。壳聚糖磁性微球对Pb2+的吸附过程基本符合Langmuir、Temkin等温吸附模型，为二级反应动力学过程。

| Abstract: | The adsorption effects on the absorbent self-made absorb Pb2+ was researched by the absorb temperature, dosage, pH, reaction time, initial concentration. The results showed that the optimal adsorb condition is the initial pH of 5.0，the reaction time of 20 min, dosage of the absorbent is 0.900 g, initial concentration of Pb2+ is 50 mg/L. The adsorption isotherms of magnetic chitosan microsphere adsorb Pb2+ well fit Langmuir's, and Temin's models, belongs to pesuo-second-order reaction. |
