Abstract

>This work presents a low-cost method to produce Zinc oxide (ZnO) nanostructured materials for the treatment of water polluted with model organic pollutants (e.g., brilliant green dye). Zinc oxide was prepared using the thermal solvent technique at a temperature of 37°C, at pH 6, and the samples were incinerated for one hour at a temperature of (500°C). Also, silver doped ZnO (Ag-ZnO) was prepared by photo deposition using ultraviolet rays. The photodissociation of Brilliant green dye was studied using ultraviolet rays under different conditions in the presence of Ag-ZnO, studying the effect of some factors, such as the effect of dye concentration and intensity of incident light. The results showed that the smashing efficiency of the zinc oxide surface increased by 92.8% after adding silver. It also showed that the photocatalytic breakdown rate increases with decreasing concentration of Brilliant green dye. Increasing the intensity of the light led to an increase in the rate of photocatalytic breakdown.
