 en Magnetic sweet graphene nanosheets: preparation, characterization and application in removal of methylene blue
Namvari, M. & Namazi, H.

Abstract

Magnetic glucose-functionalized graphene nanosheets (GNS) were prepared, and the application of these biosorbents in the removal of methylene blue was investigated. Fe3O4 nanoparticles were deposited on sweet GNS using coprecipitation. The nanocomposites were analyzed by Fourier transform infrared spectroscopy, field emission scanning electron microscopy, transition electron microscopy, vibrating sample magnetometer and X-ray diffraction spectrometry. The resulted magnetic sweet GNS were superparamagnetic, responded quickly to an external magnetic field and exhibited efficient adsorption toward methylene blue, as a cationic dye. Noleachingwas observed even after aweek of placing amagnet close to the vial containing the solution ofmagnetic sweet GNS.
