Photocatalytic Degradation Studies of J-Acid under Visible Light and Ultrasonic Activation Using Dye Sensitised TiO2

Article Preview

Abstract:

The work presented in this paper is focused on the influence of dye sensitized TiO2 for the elimination of a toxic dye intermediate J-acid (6-Amino naphthol-3-sulphonic acid). Effect of catalyst concentration, pH, initial concentration, H2O2 and ultrasound on the photocatalytic degradation of the dye intermediate was studied using an immersion well slurry reactor. A comparison of the catalytic activity of dye sensitized TiO2 with UV 100 and ZnO photocatalysts under visible light illumination was also done.
