The influence of Operational Parameters on the Photocatalytic Decolorization of Tubantin blue BRR-HC dye in pure aqueous TiO2 Suspensions

Abstract

Photo-catalytic decolorization of Tubantin blue BRR-HC dye was investigated using pure TiO2 anatase in aqueous suspension under solar radiation. The influence of pH solution, amount of catalyst, dye concentration, volume of 30% hydrogen peroxide and irradiation time was she died. Temperature of solution and photon flux were calculated during the experiments. Results show that the employment of efficient photo-catalyst and selection of optimal operational parameters might lead to complete decolorization
