REMOVAL OF IRON (II) FROM POLLUTED WATER USING ZNO NANOPARTICLES

Abstract

For the manufacture of ZnO nanoparticles, sol gel method was used. using ethanol as a solvent and zinc acetate as a primary material. sodium hydroxide was added in order to form zinc hydroxide. the synthesized hydrated zinc oxide nanoparticles were annealed at 600 °C in the air. Using field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectroscopy (EDX), the morphology of zinc oxide surface was examined. Fourier transform infrared (FTIR) analysis was used to characterize the functional groups. The Debye-Scherrer equation was used to calculate the size of the particles using X-ray powder diffraction (XRD). ZnO nanoparticles are created as a spherical structure with average (25-90) nm. These nanoparticles were successfully used in the investigation to act as adsorbents, and a high value of adsorption percentage reached to 97.9%.
