综述了硫酸根自由基(SO^-₄·)的形成及SO^-₄·降解各类污染物的机制,重点综述了近年来国内外研究的几种常见铁基材料(零价铁、亚铁、含铁矿物)活化过硫酸盐(PS)的机制,探讨了各种铁基材料的优缺点与研究现状,对相应材料不足之处进行改进。最后,对铁基材料活化PS现存问题进行梳理,并对铁基材料活化过硫酸盐技术的发展进行了展望。

The formation of sulfate radicals (SO^-₄·) and the mechanism of SO^-₄· in degrading various pollutants are reviewed,with focus on the activation mechanism of persulfates by several common iron-based materials (zero-valent iron,ferrous iron,iron-containing minerals) studied in the world in recent years.The advantages,disadvantages and research status of various iron-based materials are evaluated,and the shortcomings of corresponding materials are improved.The existing problems in iron-based materials activated persulfates are sorted out,and the development of iron-based activating persulfate technology is prospected.
