摘要
络合剂强化Mn(Ⅱ)活化高碘酸盐(PI)氧化降解水中有机污染物近期受到广泛关注,但对络合剂在其中的增强机制和高价态锰氧物种(MnRSs)的产生机理却缺乏相应的综述。本文通过与Mn(Ⅱ)/PI体系对比,分析了三种代表性络合剂在Mn(Ⅱ)/PI体系中的增强作用及其增强机制,提出了络合剂在体系中的四个作用,总结了MnRSs的鉴定方法,并分析了其优缺点,最终提出了可行的MnRSs鉴定方案。最后,对络合剂强化Mn(Ⅱ)活化PI体系中仍未解决的科学和技术问题进行了展望,提出了可行的解决方法,这将激发更多的基础研究和技术开发,有效促进该技术在实际废污水中的应用。
Chelating reagents(CRs)modified Mn(Ⅱ)/periodate(PI)systems have recently received widespread attention.However,a comprehensive and critical review on the enhancement mechanism of CRs and the generation mechanism of high-valent manganese oxide species(MnRSs)remains scarce.In this review,by comparing with the Mn(Ⅱ)/PI system,the roles and enhancement mechanisms of four typical CRs are analyzed,thereby proposing the four roles of CRs that play in the CRs/Mn(Ⅱ)/PI system.Furthermore,identification methods of MnRSs,and their advantages and disadvantages are summarized,and a feasible solution to identify MnRSs is put forward accordingly.Finally,unsolved scientific and technical issues about the CRs/Mn(Ⅱ)/PI process are identified,and the corresponding possible solutions are tentatively provided,which will stimulate more basic research and technological development,effectively promoting the application of the CRs/Mn(Ⅱ)/PI process in actual wastewater treatment.
