Abstract The escalating contamination of water bodies with antibiotic residues is an urgent environmental and public health issue. This study aimed to fabricate innovative photocatalytic composite (CMZ) by combining chitosan, magnetic iron oxide (Fe 3 O 4 ), zinc (ZnO) for efficiently removing moxifloxacin (MFX) water. Comprehensive characterization the fabricated CMZ was performed using various techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, scanning electron microscopy (SEM), energy-dispersive (EDX), ultraviolet–visible diffuse reflectance (UV–Vis DRS), photoluminescence (PL) nitrogen adsorption/desorption isotherm analysis. synergistic incorporation ZnO, Fe , chitosan in altered structural properties ZnO band gap energy 2.58 eV, significantly boosting its effectiveness under visible light exposure. composites exhibited a high efficiency catalyzing MFX degradation aqueous environments. optimal conditions were established, including neutral pH level 7, 90 min exposure irradiation, employing 0.1 g catalyst. process obeyed closely first-order kinetic model. material showed consistently performance degrading across four consecutive reuse cycles, emphasizing practical applicability mitigating pollution.
