Synthesis of Graphene Oxide Modified Magnetic Chitosan Having Skin-Like Morphology for Methylene Blue Adsorption.

In this work, a novel magnetic biomass adsorbent was synthesized by a simple method. The adsorbent prepared from chitosan, graphene oxide and CoFe₂O₄ with a 'skin-like' morphology had a strong adsorption capacity for methylene blue adsorption and was easily separated from the liquid. The synthesized samples were characterized by scanning electron microscope, energy dispersive spectroscopy, fourier transform infrared spectroscopy and X-ray diffractomer.
