| 摘 要： | 基于过一硫酸盐(PMS)的高级氧化技术因反应快速高效、降解有机污染物效果优越，在环境修复领域拥有广阔的应用潜能。经过活化的PMS化学氧化技术在有机污染废水处理中被广泛应用，污染物的去除机制也在不断被发现并完善，其在有机污染土壤修复中也已得到应用。本文综述了PMS对有机污染物的化学氧化机制，分析了有机污染物降解的自由基和非自由基反应过程，探讨了不同活化方式(碱、过渡金属、碳基材料、辐射等)对PMS降解有机污染物的影响，阐述了PMS在有机污染土壤修复中的研究进展和存在问题，并进行了研究展望。

| Abstract: | Advanced oxidation technology based on peroxymonosulfate (PMS) has broad application potential in the field of environmental remediation due to its rapid and efficient reaction and superior degradation effect of organic pollutants. Activated PMS chemical oxidation technology has been widely used in organic contaminated wastewater, and the removal mechanism of pollutants has been constantly discovered and improved, and it has also been applied in the remediation of organic contaminated soil. This paper reviews PMS chemical oxidation of organic pollutants and analyzes the free radical and the nonradical degradation mechanism. The different activation methods (alkali, transition metal and carbon material, radiation, etc.) for PMS and influence mechanism are discussed, and PMS application in the remediation of organic contaminated soil is also elucidated and prospected. |
