Electrochemical textile dye removal using steel wool as an extended electrode

The current study suggests the utilization of steel wool as an extended anode electrode in an electrochemical process to en­hance the efficiency of Remazol Brilliant Blue R (RBBR) re­moval from wastewater. The effect of the operating parameters of initial pH, applied current, supporting electrolyte, and initial dye concentration on textile dye removal efficiency was inves­tigated to determine the optimum conditions of the process. Ki­netic studies were performed in the optimum conditions. Scan­ning electron microscopy (SEM) and x-ray fluorescence (XRF) were carried out to determine the morphology and characteri­zation of the extended anode surface. Under the optimum con­ditions, the dye and chemical oxygen demand (COD) removal were obtained 99.42% and 72.72%, respectively. The reaction kinetic data of the electrochemical process was followed by the pseudo-second-order kinetic rate equation (R2 = 0.99). These findings might be useful in treating the various pollutants in industrial wastewater.
