CoFe2O4S(IV)O2 system is proposed as a new system of sulfate radical based AOPs. Alkaline pH favors the activation of sulfite on CoFe2O4 surface to produce oxysulfur radicals. Generation of CoOH complexes on the surface of CoFe2O4 is the main factor for sulfite activation. Degradation of organic contaminants by CoFe2O4S(IV)O2 system were achieved. Main intermediates and pathways for the degradation of metoprolol were identified.
