EFFECTIVENESS OF ZNO/MGO BINARY OXIDE NANOPARTICLES

ABSTRACT

Nanotechnology has received much attention in treating contaminated water. Co-precipitation method was employed to synthesize ZnO/MgO nanoparticles using a stoichiometrically fixed amount of MgSO₄. 7H₂0 and ZnSO₄.7H₂0 and later evaluated in removing Nickel and Cadmium contaminant in water. Charaterization of the prepared nanoparticles was done using X-rays diffraction (XRD), Scanning electron microscopy (SEM)

Fourier transform Infrared spectroscopy (FTIR). Experimental studies on batch scale were carried out, examine the effects of varying initial concentration of Metal, adsorbent dosage, Time and PH. An a linear graph of Langmuir and Freundlish Adsorption Isotherm of Nickel and Cadmium was plotted. Adsorption isotherm studies confirm that adsorption of the metal ion on the test adsorbent with good mathematical relation fits into Langmuir and Freundlich isotherm.
