金属活性中间体在亚硫酸盐活化技术中的产生和作用研究进展

Recent Advances of the Generation and Role of Active Metal-Oxo Intermediates in the Sulfite Activation Process

近年来,金属活性中间体在亚硫酸盐(S(IV))活化技术中的产生和作用受到广泛关注,但是,金属活性中间体的产生使得S(IV)活化技术中的机制更为复杂。目前文献关于S(IV)活化技术的研究主要集中在新体系的开发,鲜有研究对金属活性中间体在S(IV)活化技术中的产生和作用进行较为详细的分类与总结。基于此,从不同金属活性中间体的类型出发,总结了金属活性中间体在S(IV)活化技术中的产生及其鉴定方法;从污染物的性质、S(IV)的浓度、pH和溶解氧四个方面阐述金属活性中间体在S(IV)活化技术中的作用。针对目前S(IV)活化技术的研究现状和需求进行展望,以期为S(IV)活化技术在水污染控制领域的应用提供参考。

In recent years,the generation and role of active metal-oxo intermediates in the sulfite(S(IV))activation processes have received increasing attention.Nevertheless,the involvement of S(IV)activation process usually makes the mechanism of a S(IV)activation process complicated.Previous researches mainly focused on the development of new S(IV)activation methods but few researchers have classified and summarized in detail the generation and role of active metal-oxo intermediates in the S(IV)activation processes.Therefore,this study concluded the generation and identification of active metal-oxo intermediates in the S(IV)activation processes based on the different types of active metal-oxo intermediates and systematically illustrated the effect of the properties of contaminants,initial concentrations of S(IV),pH,and dissolved oxygen on the role of active metal-oxo intermediates in the S(IV)activation processes.Finally,the future advances were proposed based on the current research status and demands about the S(IV)activation processes to lay the foundation for the application of S(IV)activation processes in the control of water pollution.
