Decolorization of Reactive Dye Wastewater by Electrocoagulation

Abstract

Electrocoagulation is an electrochemical technique for treating polluted effluent, such as dye wastewater. In this paper, Remazol Brilliant Blue R was decolorized by electrocoagulation method used iron electrode. The operating cost was also considered to confirm the optimum operation conditions. High decolorization efficiency (>99%) for Remazol Brilliant Blue R dye solution was obtained with 15mA cm-2 of current density, 10min of electrolysis time, pH 6 and 500mg l-1 dye concentration.
