| description |
Electrochemical decolorization of direct black textile dye was studied in the presence of sodium
hydroxide (NaCl). Electrochemical cell occupy about 1 liter of working electrolyte supplied with graphite
electrodes for both anode and cathode was constructed for this purpose. Decolorization percent, treatment time, power consumption, and pH were studied as a function of the applied voltage and salt concentration. Results show that decolorization increase with increasing salt concentration and applied voltage. Best decolorization of 86% can be achieved after 17 min at 7 volt and 5 g/l salt concentration. Further decolorization can be achieved but this will be accompanied with a sharp increase in power consumption. No significant decrease in pH value was observed at the end of each experiment.
