Study on the synthesis and characterization of CoTiO₃ catalysts and their catalytic properties in Oxone activation for the degradation of tetracycline antibiotic in water

Abstract The chemical degradation of sulfate by activated Oxyone has the advantages high capacity, wide pH range and convenient transportation storage, making it one most attractive advanced oxidation processes (AOPs). Besides, Co is metal capable activating Oxone to produce sulfate. Therefore, critical develop Co-based catalyst, an effective recyclable heterogeneous for degrade tetracycline. In this study, CoTiO 3 was extensively investigated activation generate radicals tetracycline antibiotics. results showed that more than 95% tetracyclines could be degraded at amount catalyst 0.02 g, reagent concentration 0.4 mmol l −1 , value 7. removal rate still reach 85% after composite repeatedly used four consecutive cycles. These indicate /Oxone can explored as system degrading long-lived organic pollutants.
