Abstract:
In recent years, the indirect electrochemical degradation of industrial effluents has gained popularity. This study examines the electrochemical aqueous solution degradation of reactive azo dyes employing graphite carbon electrodes as a possible catalyst. The findings suggested that the degradation of dyes was significantly influenced by the starting pH and the supporting electrolytes. Studies on chemical oxygen demand (COD) and UV-Vis were used to assess the effectiveness of the degrading process. Reactive dye may be used to obtain maximum colour removal efficiencies of 99% and chemical oxygen demand (COD) removal efficiencies of 88%. The LC-MS investigation indicated the breakdown of reactive dye and verified that the azo groups and aromatic rings were eliminated.
