摘　　要：采用共沉淀法制备了片状纳米氢氧化镁,并进行了XRD,TEM表征。在此基础上,研究片状纳米氢氧化镁对水溶液中铅离子的吸附性能,考察了吸附时间、吸附剂加入量、铅离子初始浓度、振荡速度对吸附性能的影响。单因素条件实验确定较适宜的吸附条件为:吸附时间40min,氢氧化镁加入量1g/L,铅的初始浓度200mg/L,振荡速度为140rpm。Nanoflake magnesium hydroxide was prepared via co - precipitation process and was characterized by XRD and TEM. On that basis,treatment of lead ion by adsorption with nanoflake magnesium hydroxide was studied,and the effects of adsorption time, addition of magnesium hydroxide, initial lead ion concentration, hunting speed on adsorption performance were investigated. The adsorption conditions optimized by single - factor experiments were as follows：adsorption time 40mins,addition of magnesium hydroxide lg/L,initial lead ion concentration 200 mg/L,and hunting speed 140 μm.
