Abstract

In this paper, photo catalytic degradation of commercial textile AZO DYES catalyzed by TITANIUM DIOXIDE and modified TITANIUM DIOXIDE with Ag metal (1% w/w) in aqueous solution under irradiation with a 400 W high-pressure mercury lamp is reported. The effect of various parameters such as irradiation time of UV light, amount of photo catalyst and flow rate of oxygen, pH and temperature for the Ag-TiO2 photo catalyst were investigated. Kinetic investigations of photo degradation indicated that reactions obey improved Langmuir-Hinshelwood model and pseudo-first-order law. The rate constant studies of photocatalytic degradation reactions for Ag-TiO2 and TiO2 photo catalysts indicated that in all cases the rate constant of the reaction for Ag-TiO2 was higher than that of TiO2.
