A comparative investigation on the decomposition of triclosan via synthesized heterogeneous nano-catalysts in the presence of peroxymonosulfate

Advanced oxidation (AOPs) utilizing peroxymonosulfate (PMS) are efficient processes for the degradation of organic pollutants. This study aimed to synthesize and characterize cobalt ferrite (CoFe2O4), graphene oxide (GO), MIL-101(Fe), and their composite structures. The nanomaterials were applied as catalysts by PMS for triclosan (TCS) decomposition. The maximum removal rates of TCS were 49.29, 66.13, 84.04, 89.73, and 100% for PMS alone, CoFe2O4, GO, MIL-101(Fe), and CoFe2O4/MIL-101(Fe)/GO with PMS, respectively. Metal ions leaching declined in CoFe2O4/MIL-101(Fe)/GO/PMS compared with others. Hence, the composite nanomaterials appear to be effective catalysts for the degradation of organic pollutants by PMS activation.
