Electrochemical degradation of reactive industrial textile dye using graphite as potential catalytic electrode

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.
