Abstract

In the textile industry, textile industry wastewater is an important environmental problem due to very high water consumption and excessive use of chemicals/dyes. Chemical and classical biological activated sludge systems are generally used in the treatment of textile industry wastewater, and although organic matter removal is achieved in these wastewaters, the toxic components and color they contain cannot be removed with these treatment systems. Methods such as chemical reduction-oxidation, coagulation-flocculation, adsorption are used for color removal from wastewater, but these methods have disadvantages such as harmful by-products or sludge formation [1]. Therefore, advanced oxidation processes have been widely used in recent years because they transform toxic and permanent organic materials into harmless end products [2]. Photocatalytic advanced oxidation process converts dye molecules into end products such as CO2 and H2O by forming hydroxyl radical with catalyst and UV light. In this study, the synthesis of ZnO, which is used as a semiconductor material in photocatalytic studies, its decoration with PVP stable Ag(0) nanoparticles, and the usability of these materials in the photocatalytic degradation of methylene blue were investigated.
