This study is concerning the decolorization of direct blue dye by electrochemical oxidation technique. Laboratory testing was performed using graphite and stainless steel plates as the anode and cathode, respectively. The tests were performed using synthetic wastewater instead of real textile wastewater. The effect of operational factors (pH, dye initial concentration, the concentration of electrolyte, electrical supply voltage and run duration) were determined to study the efficiency of electrochemical oxidation for the removal of direct blue dye. The results have revealed that the maximum efficiency of direct blue removal was 98% under the optimum factors (pH of 2, dye initial concentration of 100 mg/L, NaCl of 500 mg/L and 5 V voltage).
