摘要
近年来,基于亚硫酸盐的高级氧化技术(S(Ⅳ)-AOPs)受到广泛关注,但活化S(Ⅳ)过程中涉及各种含硫自由基和非自由基物种的转化,使得S(Ⅳ)-AOPs的反应机制较为复杂,同一种S(Ⅳ)-AOP的反应机制常常存在争议.然而,鲜有研究对现有的S(Ⅳ)-AOPs及其反应机制进行较为详细的分类与总结.基于此,总结了 S(Ⅳ)的理化性质以及S(Ⅳ)-AOPs中含硫自由基的转化机制,综述了各类活化S(Ⅳ)的方法,系统阐述了 S(Ⅳ)-AOPs的反应机制、活性氧化剂的产生及贡献,解析了影响S(Ⅳ)-AOPs氧化水中污染物效能的因素.针对目前S(Ⅳ)-AOPs的研究现状和需求进行展望,以期为S(Ⅳ)-AOPs在水污染控制领域的应用提供参考.
Abstract
Sulfite-based advanced oxidation processes(S(Ⅳ)-AOPs)have received increasing attention in recent years.The S(Ⅳ)activation process involves the transformation of various sulfur-containing radicals and non-radical species,which usually makes the mechanism of a S(Ⅳ)-AOP complicated and controversial.However,the existing S(Ⅳ)-AOPs and their reaction mechanisms were rarely classified and summarized in detail.Therefore,this study concluded the physicochemical properties of S(Ⅳ)and the transformation mechanism of sulfur-containing radicals,reviewed various methods for activating S(Ⅳ),systematically illustrated reaction mechanisms in S(Ⅳ)-AOPs as well as the generation and contribution of active oxidants,and analyzed factors influencing the efficacy of contaminants degradation by S(Ⅳ)-AOPs.Finally,the future advances were proposed based on the current research status and needs about SⅣ)-AOPs to lay the foundation for S(Ⅳ)-AOPs application in the control of water pollution.
