Abstract :The effects of process parameters were investigated on the electrochemical oxidation of textile dyeing wastewater containing Acid Violet 7 insert ignore into journalissuearticles values(AV7); at Pt/Ir electrodes in the presence of 75%NaCl+25%Na 2 CO 3 insert ignore into journalissuearticles values(w/w); supporting electrolyte mixture in a batch electrochemical reactor. Experimental parameters were operated in the range of 300-1500 mg/L textile dye concentration, 4-20 g/L electrolyte concentration, 5-15 mA/cm 2 current density, and 20-60 °C reaction temperature. Energy consumption decreased with increasing textile dye concentration and electrolyte concentration, and decreasing the current density. In the study, energy consumption values were evaluated for textile dye decolorization insert ignore into journalissuearticles values(t=15 min); and COD removal insert ignore into journalissuearticles values(t=120 min); as 2.7-23.3 kWh/kg dye decolorization and 50.9-317.9 kWh/kg COD removal, respectively.
