Zero valent iron (ZVI) has been extensively used for remediation of contaminated groundwater and wastewater. The removal of contaminants by alone ZVI is significantly limited by its intrinsic passive layer and influenced by the precipitation of iron (hydr)oxides on the surface of ZVI, which affects the further reaction of ZVI with contaminants. The premagnetization of ZVI and the addition of weak magnetic field (WMF) were proposed to resolve these problems. The application of a WMF is considered to be a promising and cutting-edge technology to increase the corrosion of ZVI, rejuvenate or improve the reactivity of ZVI, expand the range of target contaminants, and improve the removal efficiency of ZVI system. This study summarized the latest advances of WMF coupling with ZVI and magnetic ZVI derivative technologies for sequestration of (a) heavy metals, (b) arsenic, (c) selenium, (d) antimony, and degradation of (e) chlorinated organic compounds, (f) nitroaromatic compounds, (g) dyes, and (h) others. The remediation performance and reaction mechanisms were discussed and summarized. The results showed that WMF-ZVI and magnetic ZVI derivative technologies were the mainstream technology and had excellent remediation performance for the above contaminants. Concerning the future development and application of WMF-ZVI and magnetic ZVI derivative technologies, some suggestions are put forward and some conclusions are drawn.

零价铁（ZVI）已被广泛用于修复受污染的地下水和废水。单独的ZVI去除污染物受到其固有的钝化层的显着限制，并受ZVI表面上铁（氢）氧化物的沉淀影响，这影响ZVI与污染物的进一步反应。为解决这些问题，提出了ZVI的预磁化和添加弱磁场（WMF）的建议。WMF的应用被认为是增加ZVI腐蚀，振兴或改善ZVI反应性，扩大目标污染物范围并提高ZVI系统去除效率的有前途的尖端技术。这项研究总结了WMF与ZVI和磁性ZVI衍生技术偶联用于隔离（a）重金属，（b）砷，（c）硒，（d）锑和降解（e）氯化有机化合物的最新进展， （f）硝基芳香族化合物，（g）染料和（h）其他。对修复性能和反应机理进行了讨论和总结。结果表明，WMF-ZVI和磁性ZVI衍生技术是主流技术，对上述污染物具有优异的修复性能。关于WMF-ZVI和磁ZVI衍生技术的未来发展和应用，提出了一些建议并得出了一些结论。和（h）其他。对修复性能和反应机理进行了讨论和总结。结果表明，WMF-ZVI和磁性ZVI衍生技术是主流技术，对上述污染物具有优异的修复性能。关于WMF-ZVI和磁ZVI衍生技术的未来发展和应用，提出了一些建议并得出了一些结论。和（h）其他。对修复性能和反应机理进行了讨论和总结。结果表明，WMF-ZVI和磁性ZVI衍生技术是主流技术，对上述污染物具有优异的修复性能。关于WMF-ZVI和磁ZVI衍生技术的未来发展和应用，提出了一些建议并得出了一些结论。
