Abstract In this work, we report the applicability of NiFe2O4 loaded graphitic carbon nitride (GCN/NiFe2O4) as a magnetic photocatalyst for wastewater treatment. Herein, GCN was prepared by thermal condensation of urea and successfully loaded with NiFe2O4 nanoparticles. GCN/NiFe2O4 was characterized by FESEM, HRTEM, IR, XRD, VSM and UV visible spectral analysis. High surface area of GCN/NiFe2O4 was suitable for adsorption coupled photocatalysis. The GCN/NiFe2O4 exhibited significant photocatalytic activity for mineralization of oxytetracycline (OTC) antibiotic under solar light. The OTC was completely mineralized in 8 h during simultaneous adsorption and photocatalysis process. The rate of OTC degradation was optimal at pH 5. GCN/NiFe2O4 possessed ferromagnetic behavior and could be easily separated by external magnetic field from waste water. The excellent activity of GCN/NiFe2O4 was due to efficient separation of photogenertaed electron and hole pair. GCN/NiFe2O4 exhibited significant recycle efficiency for ten catalytic cycles.
