Abstract
A laboratory scale, undivided electrolysis cell with platinum anode and cathode was used for electrochemical oxidation of the azo dye Acid Red 73 in simulated wastewater. The influence of the supporting electrolyte, applied voltage, pH, initial dye concentration and temperature was studied, and decolorization was monitored by UV/Vis spectroscopy. Energy consumption, current efficiency and the electric energy per order have been also determined. With NaCl (1.5 g L−1) as supporting electrolyte, at a voltage of 6 V, at neutral pH (6.9) and at 25 °C, the solution of the dye (50 mg L−1) was completely decolorized within 15 min. The apparent activation energy for electrochemical decolorization was determined as −1.9 kJ mol−1.
