PHOTO CATALYTIC DEGRADATION OF CATIONIC DYE BY MGO DOPED TIO2 NANO PARTICLES UNDER UV IRRADIATION

Abstract

Metal oxide nanoparticles plays an important role in water treatment. Ultra fine 5%, 10% and 15% MgO doped TiO2 nanoparticles have been synthesized by Sol-gel method. Synthesized nano particles were characterized by XRD, SEM, FT-IR analysis. Degradation experiments were conducted with the variable such Photocatalyst dosage (10-100mg), Initial ion concentration(2-10ppm) and pH (3, 6, 9) with Irradiation time(0-100). The optimal conditions for the degradation of cationic MB were 80 Min, 6 ppm of dye concentration, acidic pH 6 and 40mg/L of catalyst dosage.
