Comparison of degradation of an environmental pollutants by nanophotocatalysts pure ZnO and ZnO doped Mg metal in aqueous solutions by UV light

ZnO doped Mg and pure ZnO nanoparticles were successfully synthesized by sedimentary method . The products were characterized by XRD and TEM.. XRD patterns showed that the doped nanoparticles had the same crystals structures as the pure ZnO nanoparticles .ZnO doped Mg nanoparticles had larger lattice volume than the pure nanoparticles. The photocatalytic degradation of indole 3- butyric acid in aqueous solutions was investigated by both pure and ZnO doped Mg under UV light irradiation in this study. In this study the effect of different parameters such as indole 3- butyric acid concentration, photocatalyst amount, PH ,Oxidant concentration ,degradation of I-3BA and optimum condition was obtained.
