In recent years, the persistence of pharmaceutical contaminants like metronidazole (MNZ) and penicillin G (PG) in water bodies has become a major environmental concern. The present research studied simultaneous degradation MNZ PG utilizing an AgZnFe2O4@Ch catalyst generated through co-precipitation technique as effective stimulator for persulfate (PS) existence UV light. structure was characterized using X-ray powder diffraction, Fourier transform infrared spectroscopy, Field emission scanning electron microscopy, vibrating-sample magnetometer, energy dispersive spectroscopy mapping. After 50 minutes reaction time under ideal operating conditions, which included 0.4 g/L catalyst, 4 mM PS, 5 mg/L PG, pH 5, highest 81.5 % 82.3 were obtained. Statistical parameters, including R2 values 0.985 0.981 indicate very good agreement between predicted observed values. Garson's method analysis revealed that PS dosage had greatest impact on degradation, while initial concentration exerted most significant influence degradation. Langmuir-Hinshelwood model surface rate constants (Kc) 0.954 (mg/L.min) adsorption equilibrium (KL-H) 0.032 (L/mg) both antibiotics, respectively. claimed mechanism illustrated by free radical scavenging studies, demonstrated SO•4- radicals main involved PG. A last investigation catalyst's regeneration it satisfactory chemical stability after five cycles usage approaches.
