Abstract :Using magnetic nanoparticles insert ignore into journalissuearticles values(MNPs); is becoming popular method to remove heavy metal ions from different waste streams because it is simple, low-cost and effective. In this study, the bare and polymer coated Magnetite Iron Oxide insert ignore into journalissuearticles values(Fe 3 O 4 ); MNPs were assessed for their adsorption capability in removing cupric insert ignore into journalissuearticles values( cu 2+ ); ions from ammoniacal spent etchant solution, which is originated from the production of Printed Circuit boards insert ignore into journalissuearticles values(PCBs);. The polymers used to coat the MNP in this study were chitosan, levan and oleic acid. The batch adsorption experiments were conducted at a temperature of 20 o C and the pH of the solution was between 9.0 and 9.5. Experimental results showed that adsorption was achieved within 2 hours, and t he maximum amount of Cu 2+ ions adsorbed by unit weight of MNP was observed by chitosan coated MNP with an adsorption capacity of 125 mg/g. In addition, Zeta potential measurements showed that all MNPs used in adsorption tests had negative surface charges at around pH 9.0. The more negatively surface charge MNPs the more copper ions they can adsorb. From this experiment it can be concluded that chitosan coated magnetic nanoparticle can be widely used for the removal of copper ions from water and wastewaters.Keywords : Copper Adsorption, Magnetic Nanoparticles, Printed Circuit Boards, Spent Etchant
