摘　　要：过硫酸盐活化高级氧化技术在处理高毒性、难生物降解有机污染物方面展现出极大的潜力,成为当前的研究热点。在多种降解体系下,羟基自由基、硫酸根自由基、单线态氧等活性氧物种的降解机理被广泛提及。活性氧物种作为降解过程中的核心要素,主要决定了污染物的降解效率、反应路径及杂质的干扰性。本论文基于过硫酸盐高级氧化技术中活性氧物种的重要性,对该降解体系中出现的主要活性氧物种及其性质进行了综述,根据活性氧物种的特性,对其降解反应的优缺点及局限做了简要讨论。最后,本文对过硫酸盐高级氧化技术的难点与挑战进行了展望。Persulfate-based advanced oxidation processes have shown significant potential in the treatment of highly toxic and biodegradable organic pollutants.The degradation mechanisms of reactive oxygen species such as hydroxyl radicals,sulfate radicals,and singlet oxygen have been widely discussed in various degradation systems.Reactive oxygen species mainly determine the degradation efficiency of pollutants,the reaction path-ways,and the interference of impurities.This paper based on the importance of reactive oxygen species in persulfate advanced oxidation technology,provides a review of the main reactive oxygen species and their p roperties in this degradation system.The paper briefly discusses the advantages,dis-advantages,and limitations of their degradation reactions.Finally,this paper offers a perspective on the challenges and difficulties of persulfate ad-vanced oxidation technology.
