Abstract
The purpose of the present research is to remove organic dyes from wastewater and mineralize it to CO2 and H2O using photocatalytic degradation process with ZnO as a primarily metal oxide and Acid Yellow99 dye as a model of the organic compound, enhancing the photocatalytic activity of the metal oxide by loading an appropriate amount of metallic silver on it, and obtain the optimum conditions of the photodegradation process which give the highest removal of organic compounds. Commercial ZnO and Ag/ZnO photocatalysts were used for the treatment of aqueous solutions containing AY99 under UV light illumination. Photocatalytic activity of commercial zinc oxide nanoparticles (ZnO) has been investigated and its photocatalytic efficiency improved by loading silver. Loading of silver on ZnO was done with various mol % (1, 3, 5, 7 and 9) of Ag, and the optimal experimental conditions were determined. A preliminary design and cost evaluation of a photocatalytic treatment unit which treats 216 m3 per day of effluents was achieved based on the experimental work
