چکیده مقاله:

This study was performed to investigate the electrochemical oxidation of a solution containing methylene blue dye by using a tin oxide (SnO۲) electrode. The effect of several operating factors such as electrolyte types, current density, initial dye concentration, and pH were investigated by following the discolorationand COD removal. The results show that the maximum color was removed by using chloride supporting electrolyte (i.e. KCl and NaCl) indicating that the indirect oxidation was promoted by the strong oxidant species (i.e. Cl۲ and ClO–) generated at the anode surface. The best experimental conditions were attained for i = ۶۰mA/cm۲, ۱% KCl and pH = ۳, in which ۱۰۰% of color was removed after ۳۰ minutes and the COD removal reached ۸۰.۹% after ۱۲۰ min. These results reveal that the anodic oxidation technique using SnO۲ electrode could be used to remove the methylene blue dye from textile wastewater.
