摘要
纳米零价铁因其还原性强、比表面积大等特点,在土壤地下水环境修复技术方面展开了广泛的研究。介绍了纳米零价铁的制备与改性方法,综述了其在土壤地下水环境中对无机和有机污染物的降解作用与实际场地修复效果。对纳米零价铁在应用中存在的问题进行了总结,并对今后的研究方向进行了展望。
Nano zero-valent iron has been widely studied in soil and groundwater environmental remediation technology because of its strong reducibility and large specific surface area.In this paper,the preparation and modification methods of nano zero-valent iron were introduced,and its effect in degradation of inorganic and organic pollutants in soil and groundwater environment and the actual site remediation was summarized.The problems existing in the application of nanometer zero-valent iron were discussed,and the future research direction was prospected.
