The Effect of UV/TiO2/H2O2 Process and Influence of Operational Parameters on Photocatalytic Degradation of Azo Dye in Aqueous TiO2 Suspension

In this work a detailed investigation of heterogeneous photocatalytic degradation of Navy blue HE2R 1 (NB), azo dye of the reactive class is presented using UV/TiO2/H2O2 process in the aqueous suspension under 8W low-pressure mercury vapor lamp irradiation. Here we also report about optimization of various experimental parameters such as effect of catalyst concentration, effect of substrate concentration, effect of H2O2 addition.
