In this paper the decolorization and degradation of synthetic and real wastewater by electrochemical oxidation method were investigated. Synthetic wastewater consisting of Mordant Red 3 (MR3) was used as a model compound. Electrochemical degradation processes were performed using Pt as an anode and Stainless Steel 304 as a cathode. In the bulk solution, the strong oxidizing potential of the chemicals were produced when the wastewater was passed through the electrolytic cell the organic pollutants were oxidized to little or harmless organic molecules, carbon dioxide and water. The results indicated that the removal of chemical oxygen demand (COD) and color were 86% and 100% respectively. The removal of COD and color increased by increasing voltage and chloride concentration at low pH.
