Abstract:The present work investigates the photoelectrocatalytical degradation Basic Blue 41 (BB 41) largely applied to dye synthetic fibers, using a semiconductor Ti/TiO2 as photoanode. 100% of degradation of 8.33 10-5 mol L-1 dye in 0.1 mol L−1 Na2SO4, pH 2 was obtained under current density of 0.40 mA cm−2 and 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-1 and a current efficiency of 51%. T… Show more
