| Abstract: | With the high redox potential of sulfate radical(SO-4·),activated persulfate oxidation technology as an emerging advanced oxidation processes(AOP) has great potential in environment engineering.It was described ways of SO-4· 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 SO-4· of treating some organic pollutants was discussed.Finally,the existing limit and prospects of activated persulfate oxidation technology in application were presented. |
| Keywords: | sulfate radical advanced oxidation processes persulfate activate environmental protection |
