摘要
近年来,电活化过硫酸盐技术作为一种新兴的高级氧化工艺,因其低能耗、氧化能力突出、pH适应范围广、环境友好等诸多优势而成为降解有机废水的热点研究方向.过一硫酸盐(PMS)因具有不对称结构相较于过二硫酸盐(PDS)更易被活化,且主要以阴离子的形式吸附于阳极,因此,阳极电活化过一硫酸盐(EA-PMS)逐渐受到了广泛关注.本文系统地介绍了阳极EA-PMS的研究进展,重点阐述了 EA-PMS体系中自由基和非自由基的生成路径及其降解有机物的机理,探讨了影响阳极EA-PMS的主要因素,并对该领域未来的机遇和挑战进行了展望.
Abstract
In recent years,as an emerging advanced oxidation process,electrically activated persulfate technology has become a hot research direction for degrading organic wastewater due to its low energy consumption,outstanding oxidizing ability,wide pH adaptation range,and environmental friendliness.peroxymonosulfate(PMS)is easier to be activated than peroxydisulfate(PDS)due to its asymmetric structure and is mainly adsorbed at the anode in the form of anion,so the anodic electrically activated peroxymonosulfate(EA-PMS)has gradually received wide attention.This review systematically introduces the research progress of anodic EA-PMS,focuses on the generation pathways of radicals and non-radicals in the EA-PMS system and its mechanism of degrading organic matter,discusses the main factors affecting anodic EA-PMS,and looks forward to the future opportunities and challenges in this field.
