Abstract

Abstract : Many academic researchers have focused throughout the last decades on the decomposition of the organic contaminants in wastewaters aided by oxide semiconductor nanostructures, as well as the manufacture of these nanomaterials using simple, environmentally, rapid, and cost-effective procedures . ZnO nanowires (or nanorods) have received a great deal of attention due to their unusual material features and outstanding performance in electronics, optics, and photonics . ZnO nanoparticles (NPs) are prepared as a seed layer for growth nanorods (NRs) and used to remove synthetic dyes to reduce their environmental impact. Visible light (200W) was used as a source for degradation of 2-(2-pyridal azo) 1,8– dihy droxynapthalene dye with assisted ZnO NPs and NRs. In three hours, ZnO NRs removed 50.4% of Azo dye. Photolysis has been proven to be the most effective method for removing pigments. XRD and SEM were used to describe ZnO NPs and ZnO NRs .
