The main purpose of this work was to assess the removal of the herbicide oxyfluorfen and chemical oxygen demand (COD) in aqueous solution using the electrocoagulation process. The results showed that the maximum removal efficiency for oxyfluorfen and COD were (98.5% and 90%), (99.2% and 85%) and (96.1% and 70.5%) at 30 min by using iron (Fe), stainless steel (S.S) and aluminum (Al) as anode respectively, at a current density of 75 mA.cm-2 and pH of 5.8. The energy consumption in the electrocoagulation process at optimum conditions (15.9, 16.65 and 14.1 KWh/m3) using Fe, SS and Al electrodes respectively. The adsorption of oxyfluorfen preferably fitting the Freundlich adsorption isotherm. The adsorption process follows the first order kinetic model with good correlation.
