钝化剂对土壤重金属污染修复研究进展

Passivating Agents on Remediation of Heavy Metal Pollution in Soils

总结了常见的钝化剂包括石灰性物质、炭材料、粘土矿物、含磷材料、有机肥和农业废弃物等对土壤重金属污染修复的原理、技术和方法。介绍了钝化剂对土壤重金属修复的效果和注意事项,并对钝化剂进行土壤重金属污染修复的前景和目前存在的问题进行了展望。

This article reviewed the principles,techniques and methods of the common passivating agents on heavy metal contaminated soil,including calcareous substances,carbon materials,clay minerals,phosphorus materials,organic fertilizer and agricultural waste. It also described the effects and precautions of those passivating agents. The outlook of the passivating agent remediation technology and the existing problems of heavy metal contaminated soil were prospected.
