In this study, Heterogeneous Electro Fenton process with Fe3O4-Mn3O4 as a catalyst was used for textile wastewater treatment. Graphite electrodes were chosen for their stability and good conductivity. Three operating factors greatly affected the removal efficiency are current density, pH and catalyst dosage. | Heterogeneous electro fenton process for textile wastewater treatment: Application OF Fe3O4-Mn3O4 as a catalyst
