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