摘　　要：在实验室条件下,用零价铁去除Pb(II)。考察了铁粉的投加量及初始pH值对去除效果的影响,并探讨了零价铁修复铅污染水体的机制,为零价铁实际修复铅污染水体提供技术参考。结果表明:零价铁可以有效修复受重金属铅污染的水体,修复效果受铁粉的投加量及初始pH值的影响;零价铁去除铅的机制为氧化还原和混凝吸附。Under laboratory conditions,Pb（Ⅱ） was removed by zero valent iron.The influence of iron powder dosage and initial pH value on removal effect was investigated,and the mechanism of repairing lead polluted water with zero valent iron was explored,providing a technical reference for actual restoration of lead polluted water with zero valent iron.The results show that zero valent iron can effectively repair the water polluted by heavy metal lead,the repairing effect is affected by iron powder dosage and initial pH value; the mechanism for lead removal with zero valent iron is redox and coagulation adsorption.
