PEG-coated magnetite nanoparticles as adsorbents surface for remove methylene blue dye from aqueous solutions

Abstract

Magnetite Nanoparticles (MNPs) of Fe3O4 have been prepared by a co-precipitation method of ferrous and ferric aqueous solution at sodium salt to controlling by the grain size of (MNPs). The prepared nanoparticles coated by polyethylene glycol, to obtain PEG-MNPs composite for the efficient removal the Methylene blue dye from the aqueous solutions. The prepared samples have characterized by several techniques like (FTIR) spectroscopy, (XRD), (AFM) and (SEM). The research testing the ability of coated magnetite as adsorbents surface for removing of methylene blue dye from the aqueous solution within variable experimental factors. The obtained data from this study revealed that high efficiency was observed and all adsorption processes well agree with Frindlesch model, the adsorption capacity increases with the pH increases, which enhances the process of dye removal.
