This study presents a sustainable strategy for FLX removal based on a biochar-supported advanced oxidation process (AOP). A bimetallic Fe/Cu-doped biochar (Fe@Cu-BC), derived from lignocellulosic waste and exhibiting a high specific surface area (646.42 m² g⁻¹), was synthesized and applied as a green catalyst to activate sodium percarbonate (SPC). By coupling natural sunlight and aeration, the Fe@Cu-BC/SPC system promoted the generation of reactive oxygen species (•OH and O₂•⁻), leading to rapid and near-complete degradation of FLX. The degradation kinetics were well described by a modified pseudo-first-order model, and transformation products (TPs) were identified to elucidate possible degradation pathways. Despite the high FLX removal efficiency, the limited reduction in total organic carbon (TOC) suggests the need for additional post-treatment for complete mineralization. Overall, this work highlights the potential of converting agricultural and packaging wastes into multifunctional heterogeneous catalysts for emerging contaminant remediation, offering a cost-effective and environmentally friendly solution for pharmaceutical-containing wastewater treatment.falseAerationAntidepressantLignocellulosic wasteMineralizationPercarbonatePhotolysis[SDGs]SDG6journal article10.1016/j.jece.2025.1205522-s2.0-105023680655
