Study the possibility of CuO an d ZnO n anoparticles for the removal of h eavy metals from waste water s abstract

This study investi gated the adsorption of Cd2+, Cu2+ , Ni2+, and Pb2+ from a queous sol utions with n ovel nanoparticle sorbe nts (ZnO, and CuO) using a range of experimental approa ches, including, pH, competing ions, conta ct time, s canning electron microscopy (S EM), transm ission elec tron micros copy (TEM),. Tests were performe d under batch conditio ns to determ ine the adsorption rate and uptake at equilibrium from si ngle and mu ltiple component soluti ons. The maximum upta ke values ( sum of four metals) in multiple com ponent sol utions were 360.6, 114. 5 mg g–1, fo r ZnO, and CuO, respectively. Sorption equilibrium isot herms could be described using the Freundlich model in s ome cases, whereas others isotherm s did not fo llow this model. Furt hermore, a pseudo-sec ond order kinetic model was found to correctly describe the experi mental data for all nanoparticles. So il solution saturation in dices showed that the m ain mechan ism of sorption for Cd 2+ and Pb2+ was adsorption whereas both Cu2+ a nd Ni2+ sor ption were due adsorptio n and preci pitation.
