Removal of methyl orange from aqueous solution by heterogeneous Electro-Fenton process using MnFe2O4/C catalyst

Abstract

In this study, the heterogeneous Electro-Fenton process using a manganese ferrite catalyst on activated carbon derived from sugarcane bagasse (MnFe₂O₄/C) was investigated for the removal of methyl orange (MO) dye from aqueous solution. MnFe₂O₄/C was synthesized by an impregnation-coprecipitation method and characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectrometer (EDS), X-ray diffraction (XRD). Electro-Fenton model using graphite electrodes. The experiment was carried out to examine the efficiency of MO removal under neutral pH conditions. The effect of various operational parameters, such as applied current, catalyst loading, initial methyl orange concentration, was investigated.
