Abstract

                                This study aimed to optimize electrooxidation process for the degradation of textile dye Acid Yellow 36 (AY 36) in waste water using graphite electrodes. The waste water was synthetically prepared and experiments were designed as the function of variables such as pH and electrolysis time. Graphite electrode was used for all the experiments and current density was fixed at 2.5 mAcm2. Electrolyte (NaCl) concentration was kept at 0.1 M, after the electrooxidation process degradation efficiency of AY 36 were analyzed through analytical parameters such as colour and chemical oxygen demand (COD). The results confirmed that the electrooxidation process could efficiently remove colour and COD from the Acid Yellow 36 (AY 36) contaminated waste water.

Key words : Electrooxidation, Acid Yellow 36, Graphite electrode, COD, Colour removal.
