Unique Mixture of (MgO-CdO) Nanoparticles as an Adsorbent for Water Treatment

Abstract

Sol- gel method of synthesis of nanomaterials. Sol gel was applied for synthesis of magnesium oxide (MgO) and cadmium oxide (CdO) nanoparticles. Using magnesium nitrate and cadmium acetate as a raw materials and sodium hydroxide as a solvent for hydrated oxide at room temperature. Hydrated Magnesium oxide and cadmium oxide nanoparticles were annealed in air at 600 °C. The characterization methods include examine the morphology of the oxides surface using field emission scanning electron microscopy (FESEM) and Energy Dispersive X-ray spectroscopy (EDX), Characterization of functional groups was performed using Fourier Transform Infrared analysis (FTIR). X-ray powder diffraction (XRD) was used for examine the size of particles using Debye-Scherrer method. MgO and CdO nanoparticles are produced into spherical structures with average crystallite sizes of (55) and (55.5) nm, respectively. The study of using these nanoparticles as adsorbents were done successfully and the high value of removing percentage of iron about 97.8% and 98.7 respectively. Moreover, the mixture of these nano oxides gives 99.2% releasing of iron ion from polluted water.
