Abstract :
The electrochemical oxidation decolorization of the azo dye wastewater containing Acid Red G (5-acetylamino-4- hydroxy-3-phenylazo-naphthalene-2,7-disulfonic sodium) was investigated. The effect of the operating parameters, such as applied voltage, dye concentration, electrolyte concentration and temperature, on the dye wastewater decolorization efficiency was analyzed. The reaction dynamics equation was obtained. The electrolysis products were characterized by GC/MS.
