Antiviral drugs, in particular those used to treat COVID-19, have been categorized as emerging pollutants recent years due their persistent presence water/wastewater. They identified environmental matrices all over the world, proving that current treatment methods cannot eliminate them from In this study, degradation of favipiravir (FAV) and ecotoxicity changes different water were investigated using UV, UV/H2O2, UV/Co-doped ZnS quantum dots (QDs) photocatalytic processes. The effects initial FAV concentration, matrices, pH, H2O2 catalyst amount on rate evaluated. Initial concentrations (50, 100, 150 μg/L) a slight effect rate. matrix composition significantly reduced rates efficiencies for QDs processes following order: wastewater plant (WWTP) effluent > tap (TW) distilled (DW). pH (4.0, 5.0, 7.0, 9.0) had remarkable enhanced 86.3 98.1% with increasing 4.0 9.0 ionization degree UV process. maximum was obtained at 7.0 removal 93.9 100% UV/H2O2 processes, respectively. Transformation products determined toxicity algae increased 50 μg/L water. Growth inhibition 50, 15.1, 33.3, 36.3% 96 h, respectively, without any treatment. After 60 min process, growth decreased below 0.5% regardless concentration. Overall, process is effective degrading aqueous matrices; however, an step required remove natural organic matter actual matrices.

ABSTRACT This study investigates the sustainable synthesis and applications of α‐Fe₂O₃@ZnO nanocomposites derived using Laurus nobilis leaf extract as a natural reducing agent, promoting eco‐friendly material development for environmental remediation. XRD analysis confirmed formation nanocomposite with crystallite size 21.48 nm, while SEM revealed porous structure uniformly distributed particles ranging from 20 to 50 nm. FTIR spectroscopy identified characteristic Fe‐O Zn‐O bonds, ensuring nanocomposite's purity. Optical showed direct indirect bandgap energies 2.80 1.16 eV, respectively, highlighting its excellent optical properties. The demonstrated remarkable photocatalytic efficiency, achieving 96.3% degradation Brilliant Cresyl Blue (BCB) dye 95.88% Rose Bengal (RB) within 120 min under sunlight irradiation. followed first‐order kinetics, rate constants 0.0241 −1 BCB 0.01875 RB. exhibited reusability, maintaining 93.5% efficiency after five cycles, structural stability throughout repeated use. These results underscore multifunctional potential green‐synthesized dye‐contaminated wastewater treatment, contributing technologies.
