Abstract	The decolorization and degradation of the synthetic aqueous solution of the Acid Orange 10 (AO10) dye on Ti/PbO$_{2}$ anode were investigated using the response surface methodology based on central composite design with three variables: current density, pH, and supporting electrolyte concentration. The Ti/PbO$_{2}$ electrode was prepared by the electrochemical deposition method. The optimum conditions for AO10 decolorization in synthetic dye solution were electrolyte concentration of 117.04 mM, pH of 12.05, and current density of 73.64 mA cm$^{−2}$. The results indicated that the most effective factor for AO10 degradation was current density. Furthermore, the color removal efficiency significantly increased with increasing current density. To measure AO10 mineralization under optimum conditions, the chemical oxygen demand (COD) and total organic carbon (TOC) removal were evaluated. Under these conditions, decolorization was completed and 63% removal was recorded for COD and 60% for TOC after 100 min of electrolysis.
