In this work, spherically shaped ZnO nanoparticles of size around 100 nm have been synthesized by sol gel process using zinc acetate dehydrate and sodium hydroxide as starting materials at room temperature. Surface morphology and microstructural characterization of the particles are carried out using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS), particle size analysis by dynamic light scattering (DLS), grain size and crystal structure using X-ray diffractometer (XRD) and Fourier transform infrared spectroscopy (FTIR). The X-ray diffraction results indicated that the synthesized ZnO particles are of single phase and the average particle sizes were about 100 nm. The synthesized nanoparticles could be applied in the treatment of industrial waste water.
