Abstract :
We have synthesized Ni-ZnO nanoparticles (NPs) by a wet-chemical route using reducing agents. The structural and optical properties of Ni-ZnO NPs were investigated by various conventional methods. The analytical potential of the Ni-ZnO NPs was studied for a selective detection of toxic Pb(II) ion using recognized ICP-OES method for environmental remediation. Data obtained from the selectivity study indicated that the selectivity of Ni-ZnO NPs phase was the most toward Pb(II) ion. However, the adsorption isotherm data of Pb(II) on Ni-ZnO NPs phase was good-match with the Langmuir-Adsorption-Isotherm, strongly supporting that the adsorption process was mainly monolayer on homogeneous adsorbent surfaces.
