过氧乙酸活化功能材料开发与水环境应用

Development and application of peracetic acid activation-oriented functional materials in water treatment

近年来,水处理消毒剂过氧乙酸(PAA)在高级氧化过程(AOPs)中受到了越来越多的关注.虽然基于PAA活化的均相体系已经得到了大量报道,但非均相活化材料具有成本低、易操控、应用性更强、反应路径多元化等优势,逐渐发展为研究的热门方向.本文首先梳理了均相活化PAA技术的研究进展,随后着重综述了基于非均相材料活化的PAA技术在水处理中的新近研究成果,总结了涉及自由基和非自由基的材料界面氧化机制,讨论了影响PAA活化除污效果的主要因素,并介绍了理论计算和模型拟合在PAA技术研究中的具体运用.最后,总结了现阶段非均相活化PAA技术研究的现状,并对未来以PAA活化功能为导向的材料开发与水环境应用进行了展望.

In recent years,peracetic acid(PAA)has gained significant attention as a disinfectant for water treatment in advanced oxidation processes(AOPs).While homogenous PAA activation systems have been extensively studied,there has been a growing interest in non-homogenous activation materials due to their advantages,including low cost,easy operability,stronger applicability,and diversified reaction pathways.In this review,we first reviewed the research progress of homogenous PAA activation technology,and then focused on summarizing the recent research results of non-homogenous material-activated PAA technology in water treatment.We elucidated the radical and non-radical oxidation mechanisms at the material interface,discussed the main factors affecting the removal of pollutants through PAA activation,and introduced the specific application of theoretical calculations in PAA technology research.Finally,we concluded the current status and shortcomings of non-homogenous PAA activation technology research and provided prospects for future material development and water environment application oriented to PAA activation functionality.
