Treatment of Petrochemical wastewater by Modified electro-Fenton Method with Nano Porous Aluminum Electrode

This research reported a study on COD removal from petrochemical wastewater (ml/l) by the electro-Fenton process via the effects of different parameters such as reaction time, current density, pH, H2O2/Fe2+ molar ratio, and volume fraction of H2O2. For this purpose, first, the Nanopores on the alumi...

Summary:This research reported a study on COD removal from petrochemical wastewater (ml/l) by the electro-Fenton process via the effects of different parameters such as reaction time, current density, pH, H2O2/Fe2+ molar ratio, and volume fraction of H2O2. For this purpose, first, the Nanopores on the aluminum ‌electrode surface were prepared as the AAO films were fabricated using the two-step anodization of 6063 aluminum alloy sheets at ambient temperature in sulfuric acid and phosphoric acid electrolyte solutions respectively.The nanostructures created on electrode confirmed by Scanning Electron Microscopy (SEM). Then, Efficiency of electrochemical oxidation process was tested by COD determination via electrolyte cell contain waste water, Fe2+, H2O2 and AAO electrode based on experimental design. The optimum COD removal (65.03%) was obtained at pH of 2.96, the reaction time of 89.51 min, the current density of 69.57 mA, the H2O2/Fe2+ molar ratio of 3.42 and volume fraction of H2O2 to petrochemical wastewater of 1.93 (ml/l).
