Degradation of Antiviral Drug Favipiravir Using UV, UV/H₂O₂, and Photocatalysis with Co-Doped ZnS Quantum Dots: Operational Parameters, Kinetic Studies, and Toxicity Assessment.

ABSTRACT: Antiviral drugs, in particular those used to treat COVID-19, have been categorized as emerging pollutants in recent years due to their persistent presence in water/wastewater. They have been identified in environmental matrices all over the world, proving that current treatment methods cannot eliminate them from water/wastewater. In this study, the degradation of favipiravir (FAV) and ecotoxicity changes in different water matrices were investigated using the UV, UV/H₂O₂, and UV/Co-doped ZnS quantum dots (QDs) photocatalytic processes. The effects of initial FAV concentration, water matrices, pH, H₂O₂ concentration, and catalyst amount on the FAV degradation rate were evaluated. Initial FAV concentrations (50, 100, and 150 μg/L) have a slight eff
