Electrochemical Oxidation of Dye by using Graphite and Titanium Based Electrodes

Abstract

The treatment of synthetic textile dye using electrochemical oxidation is found to be a very effective method for the degradation of non-biodegradable pollutants by decreasing the organic load and color. Hence the present investigation concerns with the study of various parameters such as NaCl Concentration, Electrolysis Time, Current Density, pH, Dye Concentration. These parameters influence the performance of the electrochemical oxidation process of synthetic textile dye to remove the color and COD by using Graphite and Titanium based electrodes. The result indicate that the removal of color and COD using Graphite electrode is 95.44% and 37.10% ,by using Titanium based electrode is 96.30% and 37.87%  based on optimum conditions. The removal of color and COD increased by varying NaCl Concentration, Electrolysis Time, Current Density, pH, Dye Concentration. Due to effectiveness and ease in operation, this technique can be applied for a large volume and industrial scale of textile polluted water.
