Electrochemical oxidation for Disperse blue 1 dye wastewater simulated in the laboratory, was investigated in this study using Graphite materials as the electrodes. The experiment was carried out in a batch process in a laboratory-scale that was analyzed at every 30 min regular intervals, for a total period of 180 min. the results were reported in terms of colour removal for different parameters of initial concentrations (50mg/L, 95mg/L, and 145mg/L), electrode geometry (plain and cylindrical), pH (4, 7, 9), current intensity (1A, 3A), and temperature (280C, 500C). For the different initial concentrations, Color was reduced by 85.4%, 67.4% and 67.8% respectively. More also the plain graphite electrodes showed a comparatively higher efficiency of colour removal than the cylindrical graphite electrodes. Furthermore, we observed a decrease in colour removal when the pH of the effluent was increased from 4 to 9 showing an efficiency of 58.7%, 54.6% respectively. Current intensity and temperature showed similar variations. UV-Vis study confirmed that the proposed electrochemical degradation process could be an effective method for the degradation of textile dye effluent.
