Degradation mechanisms of ofloxacin and cefazolin using peroxymonosulfate activated by reduced graphene oxide-CoFe2O4 composites

In this work, reduced graphene oxide (rGO) sheets were integrated with CoFe2O4 to construct distinctive composites that were evaluated as heterogeneous catalysts activating peroxymonosulfate (PMS) for the oxidative degradation of ofloxacin (OFX) and cefazolin (CFZ), two widely used pharmaceuticals belonging to the fluoroquinolone and β-lactam antibiotic families, respectively. The results showed that of all of the catalysts tested, the composite...
