Abstract In this research attempts were made to affect anodic oxidation of direct dye in an electrochemical reactor as a new technique for treating and decolorizing textile -wastewater. Lead spheres were used as anode and stainless steel sheet as a cathode. The reactor which was a rectangular plexyglass VDDI.ainar was zNto trio ’halves &y- means of a FVC porous diaphragm, Na 2 SO 4 was used as a supporting electrolyte in both anode and cathode compartments. A regulated D.C. power supply was used as a source of current and dye solution was continuously introduced to the electrochemical reactor from the storage tank by means of pump. 1 bypass was used to regulate dye solution flow rate to the reactor During each run, the contents of anode compartment were a lyzed spectrophotometrkcally at intervals until complete decolorization occurs. Variables were: initial dye concentration, solution flow rate, anode area (Number of lead spheres) and pas¬ *134 current. It was found that in all cases the rate of dye removal imereases with increasing the cell current and time of anodic oxidation. |
