Preparation of persulfate retarding materials and their application in groundwater organic pollution remediation

作为一种可控缓释技术,过硫酸盐缓释材料可以持续稳定释放过硫酸盐,延长了活性组分的作用时间,对地下水中污染物的修复起到了长效的积极作用,缓释过硫酸盐在地下水污染修复领域中引起广泛关注。文章从多角度对过硫酸盐缓释材料的缓释过程和作用机理进行综述,总结了过硫酸盐缓释材料的制备方法和释放机制,概括了影响过硫酸盐缓释材料综合性能的因素,以及过硫酸盐缓释氧化材料在地下水有机污染修复中的研究及应用进展,并对硫酸盐缓释材料未来的研究方向和关键问题进行展望。

As a controlled slow-release technology,peroxynitrite slow-release materials can continuously and steadily release peroxynitrite,which extends the action time of the active component and has a long-lasting positive effect on the remediation of contaminants in groundwater,and slow-release peroxynitrite has attracted widespread attention in the field of groundwater pollution remediation.The article reviews the slow-release process and mechanism of action of persulfate retarding materials from multiple perspectives,summarizes the preparation methods and release mechanisms of persulfate retarding materials,outlines the factors affecting the comprehensive performance of persulfate retarding materials,as well as the research and application progress of persulfate retarding oxidation materials in groundwater organic pollution remediation,and provides an outlook on the future research directions and key issues of persulfate retarding materials.
