Abstract

In this work, color removal of a synthesized blue indigo dye using iron electrodes in continuous electrocoagulation process was studied. The Response Surface Methodology (RSM) was used to optimize four investigated parameters: pH solution, absorbance solution or concentration, initial flow rate and voltage. The highest color removal efficiency was achieved at neutral pH range (7.5), at low absorbance (2.439 au), low flow rate (2 L/min), and at high voltage level (47 V). The higher correlation coefficient R2 (97.8%) and the ANOVA analysis confirm the high accuracy of the RSM model for the response. Under optimum conditions, the achieved color removal efficiency reached 93.972% which is in good agreement with the predicted model data 94.0834%. The calculated total cost was 0.0927 per m3 of treated effluent.
