ABSTRACT

In this study, graphite electrodes have been used for electrochemical oxidation of aqueous solution of Reactive Red 195 (RR 195). As part of electrolysis, three different electrolytes were used, including NaCl, NaNO3 and Na2SO4; and NaCl proved to be the most effective in removing the Colour of RR 195 dye from its aqueous solution. Based on the effects of the process variables dye concentration, current density, electrolyte concentration, pH and stirring speed, the highest colour removal was achieved after 90 min. At optimum operating conditions, such as 0.075% sodium chloride (NaCl) concentration, a current density of 3.75mA/cm2, pH 7, and stirring speed of 250 rpm, 94% of the color was removed. UV-Vis spectrophotometer was used to measure color removal during dye degradation. In comparison with conventional treatment techniques, this method is highly effective
