Özet:

 


Using
magnetic nanoparticles (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 (Fe3O4) MNPs were
assessed for their adsorption capability in removing cupric (cu2+)ions from ammoniacal
spent etchant solution, which is originated from the production of Printed
Circuit boards (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 20oC and the pH of the solution was between 9.0
and 9.5. Experimental results showed that adsorption was achieved within 2
hours, and the maximum amount of Cu2+ 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.
