Electrochemicaloxidation of Reactive Black5 (RB 5) was conducted for degradation using DSA type TiRuO2SnO2 Sb2O5 electrode. In the study, for electrooxidation, electrode was indigenously fabricated in laboratory using titanium as substrate. This substrate was coated using different metal oxides RuO2, Sb2O5 and SnO2 by thermal decomposition method. Laboratory scale batch reactor was used for degradation and decolorization studies at pH 2, 7 and 11. Current density (50mAcm2) and distance between electrodes (8mm) were kept constant for all experiments. Under identical conditions, removal of color, COD and TOC at initial pH 2 was 99.40, 55 and 37 respectively for initial concentration of 100 mgL RB5. Surface morphology and composition of the fabricated electrode coatings were characterized using scanning electron microscopy (SEM) and energy dispersive Xray spectroscopy (EDX) respectively. Coating microstructure was analyzed by Xray diffraction (XRD). Results of this study further revealed that almost 90 of oxidation occurred within 510 minutes.
