Oxytetracycline (OTC) is widely used in aquaculture; however, increasing residue in water has contributed to antibiotic pollution and increased antibiotic resistance. A novel nanocomposite material - g-C3N4/Bi2MoO6/Clinoptilolite (CNBC), has been demonstrated to effectively degrade OTC in water via photocatalysis in both batch and continuous systems. The composite material was successfully synthesized by the solvo-thermal process under the conditions of (a precursor ratio of 14:56:30 (g-C3N4:Bi2MoO6:Clinoptilolite). Physicochemical characterization results (FT-IR, XRD and FE-SEM, and EDX) showed that g-C3N4/Bi2MoO6 was homogeneously dispersed on the surface of Clinoptilolite. The OTC degradation efficiency was 100 % with a catalyst content of 150 mg/L, while with 500 mg/L the efficiency was only 85.81 % in the batch system. These results suggest that this nanocomposite could be an effective solution for removing OTC from water on an industrial scale, helping to solve the problem of antibiotic pollution in the aquatic environment.
