In this study, ZnO/Fe3O4 (MZ) composite material was successfully synthesized with the combination of ZnO and Fe3O4. The obtained materials were characterized by XRD, SEM, TEM, BET, VSM, and UV-Vis DRS methods. MZ composite had the ability of photocatalytic degradation of antibiotic levofloxacin (LFX) in aqueous solutions under sunlight. The results showed that the photocatalytic degradation of LFX increased as the lighting time increased and decreased as the initial concentration of LFX increased. The kinetic of LFX photocatalytic degradation by MZ followed the Langmuir – Hinshelwood pseudo-first-order kinetic model. The material had good reusability after five cycles.
