Synthesis of Zinc Nanoparticles and Its Application in Treatment of Municipal Water of Anantapur

S. Sharada | Srikanth Pusarla

Abstract: Water is polluted by the industries like construction and mining, food processing from domestic and agricultural wastes and by micro logical agents. There are different methods are worn for purification of water, but these water treatment techniques require large area, high capital investment, operation and maintenance cost. The contamination of water is a major problem in the global consequence. The metal oxide semiconductor like ZnO is capable of in service effectively and efficiently for the water treatment. ZnO nanoparticles are synthesized from direct precipitation method. Zinc nitrate showed best performance, yielding ZnO particles with the smallest average grain size. At optimal conditions, ZnO nanoparticles with average size of 16 nm were obtained. The synthesized ZnO nanoparticles were characterized by scanning electron microscope (SEM), Xray diffraction (XRD), UVVis absorption spectroscopy. After synthesis of ZnO nanoparticles, The ZnO nanoparticles are coated on filter candles by using non-woven fiber. These filter candles are fitted into the equipment of water filteration. The treatment of nanoparticles to the drinking water has been examined by various water testing analysis. The work resulted Economically feasible and Environmental freindly in all aspects.
