▎ 摘　　要

The application of nanomaterials in water treatment has attracted significant attention recently. graphene/Fe3O4 nanocomposites (G/Fe3O4) with different ratios were prepared by solvothermal method and characterized using X-ray diffraction (XRD), high resolution transmission electron microscope (HR-TEM), vibrating sample magnetometer (VSM), and X-ray photoelectron spectroscopy (XPS), The effect of the composition ratios on the removal of methylene blue dye (MB) from aqueous solutions was investigated.
