摘要
由于硫酸自由基(SO4-.)具有很高的氧化还原电位,过硫酸盐(S2O82-)活化高级氧化技术作为一种新型氧化技术在环境工程领域具有巨大应用潜能。介绍了热活化、光活化、过渡金属离子三种活化过硫酸盐产生SO4-.的方式,在环境保护方面的现状研究与应用进展,主要涉及受有机污染土壤和地下水的修复、难降解有机废水和废气的处理,阐述了SO4-.高级氧化技术处理各种有机污染物的机理,指出了基于SO4-.的高级氧化技术在处理应用中存在的局限性和未来发展方向。
With the high redox potential of sulfate radical （ SO4^-·） , activated persulfate oxidation technology as an emerging advanced oxidation processes （AOP） has great potential in environment engineering. It was described ways of SO4^-· generation from persulfate activation catalyzed by heat, ultraviolet and transition metal. Furthermore, it was focused on the up- to-date research and application in environmental protection field, which mainly involves remedy of contaminated soil and groundwater and treatment of refractory organic wastewater and gas. Moreover, the mechanism associated with SO4^-· of treating some organic pollutants was discussed. Finally, the existing limit and prospects of activated persulfate oxidation technology in application were presented.
