摘要:

基于硫酸根自由基(sulfate radical,SO4 -·)氧化原理的活化过硫酸盐(persulfate,PS)氧化法是近年来高级氧化工艺(advanced oxidation process,AOP)的研究热点,以经济、高效、环境友好、安全稳定的优势在水处理、环境保护等领域开辟了新的思路。此前,学者们发现过硫酸盐高级氧化根据活化反应条件(如温度、光照、pH、过渡金属及催化剂等)的不同,会产生不同的自由基参与氧化反应,对降解结果也会产生不同程度的影响。本文根据相关自由基氧化机理,从产生硫酸根自由基的单一氧化、复杂活化体系硫酸根自由基与其他自由基复合氧化以及强化降解等方面,分析了近几年国内外学者对过硫酸盐降解典型有机污染物的研究及在催化剂开发方面所做的工作,指出了许多新颖的过硫酸盐活化手段及其降解效果与不足,并就未来的发展进行了展望,以期为过硫酸盐氧化法未来更好地发展和应用探索出路。

Abstract:

Activated persulfate (PS) oxidation based on the oxidation principle of sulfate radical (SO4 -·) is a hot research topic of advanced oxidation process (AOP) in recent years. Since activated persulfate oxidation is economical, efficient, environmentally friendly, safe and stable, it gives out new countermeasures in water treatment, environmental protection and other fields. Previously, scholars found that the activated persulfate oxidation had different free radicals involved in the oxidation reaction with different reaction conditions such as pH, catalysts, which lead to varying degrees of influence in degradation results. Based on the relevant radical oxidation mechanism, including single oxidation with sulfate radical, synergistic oxidation with sulfate radical and the other enhanced catalytic activation, the domestic and foreign scholars’ research on the degradation of typical organic pollutants by persulfate was analyzed. Besides, the work on catalyst development was studied, and many novel activated methods of persulfate and its degradation effect and deficiency were pointed out. Furthermore, the way out for better development and application of persulfate oxidation method in the future was explored.

Key words: activated persulfate, advanced oxidation process, sulfate radical, hydroxyl radical, organic pollutants
