零价纳米铁在修复受污染地下水中的最新进展

摘要

To solve the problems existing in remediation of contaminated groundwater using nanoscale zero-valent iron （nZVI） such as aggregation, low migration and aging, some new progresses in this field were introduced in this paper in detail including modified nZVI and its effect on degradation of pollutants as well as different factors else. In addition, the degradation of recalcitrant organic pollutants by nZVI was summarized. And then the degradation of some special materials such as emerging pollutants, pharmaceuticals and personal care products （PPCPs） was prospected.%本文针对零价纳米铁（nZVI）在修复受污染地下水中存在的易于团聚、迁移性低及易于老化等问题,详细介绍了近年在这些问题研究上的最新进展,包括材料的改性,改性材料对污染物降解的效果及研究中不同因素的影响等。并就nZVI对难降解复杂有机污染物的降解进行了总结,在此基础上展望了nZVI对一类新兴污染物,药品和个人护理用品（PPCPs）的降解。
