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. Cl2 and ClO–) generated at the anode surface. The best experimental conditions were attained for i = 60mA/cm2, 1% KCl and pH = 3, in which 100% of color was removed after 30 minutes and the COD removal reached 80.9% after 120 min. These results reveal that the anodic oxidation technique using SnO2 electrode could be used to remove the methylene blue dye from textile wastewater.}, keywords = {Oxidation,Dyes,Discoloration,Methelyne bleu,SnO2 electrode}, url = {https://ijcce.ac.ir/article_34227.html}, eprint = {https://ijcce.ac.ir/article_34227_c732257f410bcf40c8700d63666c3946.pdf} }
