Furazolidone, a nitrofuran antibiotic, has been broadly used in aquaculture and veterinary medicine, its presence water poses considerable environmental health hazards due to toxicity. This study investigated hybrid photocatalytic process for the removal of furazolidone, employing graphitic carbon nitride (g-C3N4) persulfate anions (PS) under both laboratory pilot-scale conditions. The synergistic effect g-C3N4 PS enhanced generation reactive species, facilitating efficient degradation FZ two different aqueous matrices. Through scavenging studies, positive holes were determined be dominant followed by sulfate radicals. Seven transformation products tentatively identified via UHPLC-LTQ/Orbitrap MS analysis. optimized system (g-C3N4/PS) achieved 100% furazolidone less than 60 min simulated solar light, demonstrating potential large-scale application wastewater remediation. Furthermore, experiments using real secondary treated municipal proved that applied is capable achieving an 86.2% (k = 0.017 min−1) as well 90% decrease effluent ecotoxicity within 120 UVA irradiation. provides insights into sustainable processes antibiotic contaminants from underscores role g-C3N4-based approaches upper-scale applications.
