摘　　要：在众多水处理技术中,过硫酸盐高级氧化法(AOPs)因其产生高活性的硫酸根自由基(SO_(4)^(·-))以及羟基自由基(·OH),具有高效的矿化能力,受到越来越多的关注。开发了一种安全、经济、环保的过硫酸盐高级氧化法处理有机污染物的活化技术。光催化是一种绿色、环保的过硫酸盐活化方法,过硫酸盐体系中的光催化剂可以提高光的利用率,将过硫酸盐转化为活性物种降解有机污染物。首先从作用机理介绍了不同过硫酸盐在反应体系中的选取,讨论了金属基光催化剂的活化,介绍了在实际应用中面临的挑战,并结合目前研究现状对未来发展方向进行展望,为过硫酸盐活化技术在处理污染物应用上提供一定的参考。Among many water treatment technologies,advanced oxidation of persulfates(AOPs)has received increasing attention due to its efficient mineralisation ability by generating highly reactive sulfate radicals(SO_(4)^(·-))as well as hydroxyl radicals(-OH).A safe,economical,and environmentally friendly activation technology for the treatment of organic pollutants was developt by advanced oxidation of persulfate.Photocatalysis is a green and environmentally friendly method of persulfate activation,and the photocatalyst in the persulfate system can improve improve the utilisation of light and convert persulfate into active species to degrade organic pollutants.The selection of different persulfates in the reaction system from the mechanism of action were introduced,then the activation of metal-based photocatalysts were discussed,and the challenges faced in practical applications were introduced,and the future direction of development in the light of the current state of research was looked forward,and the certain reference for the application of persulfate activation technology in the treatment of pollutants were provided.
