Özet:

 

We report a facile method to produce a magnetically separable graphene  oxide--magnetite nanocomposite (GO--Fe3O4) and its  adsorption performance in methylene blue (MB) removal from aqueous solution.  The GO--Fe3O4 nanocomposite was synthesized by a solution-phase  self-assembly method including the incorporation of monodisperse  Fe3O4 nanoparticles (NPs) and GO in a dimethylformamide/chloroform  mixture under sonication. The successfully decorating GO sheet with  monodisperse Fe3O4 NPs was proved by TEM study. ICP--OES data of  the GO--Fe3O4 nanocomposite show that the GO--Fe3O4  nanocomposite consists of 21 wt% Fe3O4 NPs, which is sufficient  for its magnetic separation from aqueous solution. The spectroscopic studies  reveal that the GO--Fe3O4 nanocomposite is a highly efficient  adsorbent for MB removal from aqueous solution, providing an adsorption  capacity of 172.6 mg/g, and the equilibrium for MB adsorption is attained in  \sim 70 min. Moreover, it is a magnetically separable and reusable  material for MB removal from water, preserving 87% of its initial  efficiency after 5 successive runs.
