Removal of methylene blue from aqueous solution by a solvothermal-synthesized graphene/magnetite composite

- The graphene/Fe3O4 composite was synthesized by in situ conversion of FeCl3 to Fe3O4 and simultaneous reduction of GO into graphene in ethylene glycol solution.
- The adsorption process was characterized by kinetics, isotherm and thermodynamic analysis.
- The graphene/Fe3O4 composite could be utilized as a magnetically separable and efficient adsorbent for the environmental cleanup.
