Abstract

Persulfate (PS, S2O8-2) has a standard oxidation potential making it use for treatment of a wide range of pollutants. It is also used within Advanced oxidation processes (AOPs),where Sulfate radicals (SR) can be effectively generated through PS activation by physical methods (such as heating, UV) and chemical methods (including transition metal ions, alkaline conditions), as well as coupling activation methods. Overall, SR-AOPs not limited applied to the treatment of refractory organics in wastewater but also are efficient in dealing with novel/emerging pollutants.
