Resumo: The present work investigates the photoelectrocatalytical degradation Basic Blue 41 (BB 41) largely applied to dye synthetic fibers, using a semiconductor Ti/TiO2as photoanode. 100% of degradation of 8.33 10-5mol L-1dye in 0.1 mol L-1Na2SO4, pH 2 was obtained under current density of 0.40 mA cm-2and irradiation UV after 60 min of treatment and 80% of total organic carbon removal. The oxidation follows pseudo-first order reaction with initial rate constant of -0, 040 mim-1and a current efficiency of 51%. The results are superior the conventional photocatalysis in the same conditions without the polarization of the photoanode that takes to 65% of mineralization under initial rate constant -0, 024 min-1
