Abstract
ABSTRACT: Electrochemical and photochemical techniques have been proved to be effective for the removal oforganic pollutants in textile wastewater. The present study deals with degradation of synthetic tex-tile effluents containing reactive dyes and assisting chemicals, using electro oxidation and photocatalytic treatment. The influence of various operating parameters such as dye concentration, cur-rent density, supporting electrolyte concentration and lamp intensity on TOC removal has beendetermined. From the present investigation it has been observed that nearly 70% of TOC removalhas been recorded for electrooxidation treatment with current density 5 mA/dm 2 , supporting elec-trolyte concentration of 3 g/L and in photocatalytic treatment with 250 V as optimum lamp intensitynearly 67% of TOC removal was observed. The result indicates that electro oxidation treatment ismore efficient than photocatalytic treatment for dye degradation.Keywords : TiO 2 /UV, Electro oxidation, Photocatalysis, Organic pollutant, Textile effluent
