Abstract :
Fe2V4O13 is prepared and characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), UV-diffuse reflectance spectroscopy (UV-DRS), high resolution scanning electron microscopy (HR-SEM) using energy dispersive X-ray spectroscopy (EDX) analysis. The hetero-Fenton catalyst can be used to mineralize Methyl Orange (MO) under UV-A light. The mineralization rate is influenced by hydrogen peroxide (H2O2) concentration, pH, and catalyst loading. The reusability of Fe2V4O13 is analyzed by five successive runs. At the maximum, 95% of degradation is observed in all five cycles. Therefore, the Fe2V4O13 catalyst is found to be reusable. The mineralization is confirmed by chemical oxygen demand (COD) measurements. Mechanism of the heterophoto-Fenton process is also proposed.
