Heavy metals (Copper, Cadmium, Nickel, Lead and Chromium) are natural constituents ofthe Earth, usually are toxic. These metals, even at trace level, are known to be a risk forhuman beings [1]. The presence of copper, cadmium, nickel and others metals in the aqueousenvironment has a potentially damaging effect on human physiology and other biologicalsystems when the acceptable levels are exceeded [2]. In this study, magnetic nanoparticles(MNP) have been synthesized by co-precipitation method. Fe3O4 immobilized on activatedcarbon (AC). The removal of copper ions from aqueous solution by synthesized magneticactivated Carbon nanoparticles was investigated. Adsorption kinetics and isotherm modelswere found.
