Resumo: Photoelectrodes were used to treat synthetic textile wastewater contaminated with indanthrene blue dye. Two media of treatment were used (NaCl and Na2SO4), with variations on temperature, pH, current density, dye and chloride concentration. A modified Pechini method was applied to obtain Ti/Ru-based electrodes (Ti, Ru, Ti0.5Ru0.5, Ti0.75Ru0.25 and Ti0.25Ru0.75) containing anatase TiO2 nanoparticles and a color degradation analysis was done. Physical (atomic force microscopy and X-ray diffractometry) and electrochemical characterizations (cyclic voltammetry) were considered. The condition that yielded highest color removal for the system presented 0.05 mol L-1 NaCl, 100 mA cm-2, 35 °C and pH 7, independent of the dye concentration for the Ti0.25Ru0.75 electrode.
