Abstract:   (75 Views)
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.
