摘要
基于活化过一硫酸盐(PMS)产生SO_4^-·的新型高级氧化技术,在芬顿和类芬顿催化降解水中有机污染物的研究中占有重要地位。本文从活化PMS方法的特点和用途出发,对目前活化PMS的主要方法进行了论述,并对活化PMS降解水中有机污染物的机理进行了探讨,最后对该领域研究中存在的问题进行了分析。指出,开发高效的协同活化PMS的方法将成为该领域研究的必然趋势。
A new type of advanced oxidation technology based on sulfate radicals,produced by activation of peroxymonosulfate(PMS),occupies an important position in Fenton catalysis and Fenton-like catalysis for degradation of organic pollutants in aqueous solutions.In this paper,started from the traits and uses of the methods of activating PMS,the main methods of activating PMS are summarized,and the mechanisms of degrading organic pollutants in aqueous solutions by activating PMS are discussed.Finally,the existing questions in this research field are analyzed.It is pointed out that the development of an efficient method for synergistic activation of PMS will be an inevitable trend in this research field.
