In this investigation, ZnO nanoparticles were prepared by chemical precipitation method. Ethylenediaminetetra acetic acid (EDTA) was used as a capping agent. The particles were characterized by XRD, UV-Vis spectroscopy, Scanning electron microscopy (SEM), and FTIR spectroscopy. Calculation based on the XRD data reveals that the synthesized ZnO nanoparticles are of hexagonal phase with ∼ 40 nm average particle size. The surface morphology was investigated by using SEM and the elemental analysis by Energy dispersive analysis of X-rays (EDAX). Band gap was also calculated using UV-Vis spectroscopy. A standard peak of zinc oxide was observed at 480 cm-1 from FTIR spectroscopy.
