A number of batch experiments were run in a laboratory-scale that was analyzed at every 15 min regular intervals, for a total period of 60 min. The results are reported in terms of percentage removal Color. Synthetic effluent was treated with electrochemical oxidation having the stainless steel as anode and cathode. The effects of operational parameters such as current density, Effect of dye concentration (2, 5, 7, 9, 11 ppm) and effect of pH (2, 4, 6, 8, 10, and 12) on the decolourization of procion red mx5b dye was studied at optimistic condition i.e. 25V. It was observed that highest decolourization (99%) was achieved for 2 ppm concentration of procion red mx5b dye. It can be concluded from the results that SS as anode found to be effective in treating this electrolyte and could be effectively used for pretreatment.

Introduction The textile industry consumes large amount of water for different processing thereby producing large amount of wastewater. In general, the wastewater produced from textile industries is found to contain high amount of pollutants with high total dissolved solids and suspended solids. The wastewater is highly viscous and colored due to pigments and suspended solids respectively. [1-15] Dye released to the environment impart colour will directly affects the aquatic life by decreasing the reoxygention of water. The observed by many researchers that the conventional treatments like biological treatments, coagulation/ flocculation treatment do not give satisfactory results. Some techniques of treatment of textile such as Membrane separation and adsorption have the limitation for the effective treatment of textile effluent. Advance oxidation process is considered as effective and attractive treatment for the treatment of textile effluent. [2-6] Electrochemical oxidation is promising method for the textile effluent. Electrochemical treatment display high efficiency and also prevents the unwanted products. Recently electrochemical techniques have been growing with interest for the treatment of wastewater containing organic pollutants [19]. The electrochemical process contains two important features which are converting non- biocompatible organics into biocompatible compounds and oxidation of organics into carbon dioxide and water. Many researchers engaged on different electrodes like platinum, copper, zinc, nickel, stainless steel, lead acid battery, graphite, titanium, to get higher degradation efficiency. [6- 17] The objective of this study was to investigate the effect of current density, pH and initial dye concentration on electrochemical degradation (removal) of (Procion Red Mx5b) from its aqueous solution through electrochemical potential. Procion MX: Procion MX is a cold water reactive dye which could be used at normal room temperature. Fiber reactive dyes produce colour inside the fiber rather than on its surface, hence have light fastness and wash fastness. They are excellent for direct applications such as printing, spatter- painting and immersions dyeing methods.
