Dye-contaminated wastewaters are industrial wastewaters that are difficult to treat using traditional biochemical and physicochemical methods. In the present work, the acid red G was removed as a model pollutant by the electro-Fenton process for the first time. The anode and cathode used by the electro-Fenton process were iron plate and graphite felt, respectively. It was concluded that under the optimal conditions of current density = 20 mA cm–2, pH = 3 and initial Na2 SO4 concentration = M, the removal rate of acid red G (ARG) with an initial concentration of 300 mg L–1 could reach after 80 min of electrolysis. |
