Resumo: The photoeletrocatalytic oxidation of 0.009% (m/v) of commercial surfactant Tamol® in 0.1 mol L-1 Na2SO4 was investigated on thin-film of TiO2 as photoanode.Using the best experimental condition, E = + 1.0 V, pH 2.0 and UV irradiation were obtained 100% of surfactant removal followed by 94% of total organic carbon (TOC) removal after 90 min of photoelectrocatalytic treatment. The method was applied to surfactant removal in the presence of acid red 151 dye. After 90 min of treatment the method promoted 98% of discoloration concomitant to reduction of 81% total organic carbon of the resulting solution.
