•ZF-rGO nanocomposites were successfully prepared by one-pot solvothermal method.•Magnetic properties of ZF-rGO were enhanced by substituting Fe2+ for a part of Zn2+.•The composites ZF-rGO show good adsorption properties for MB removal.•Effective, rapid and easy magnetic separation property.
The wide application of reduced graphene oxide (rGO) in water treatment is mainly suffered from high cost and difficult reusage. To addressing these issues, a series of zinc ferrite-reduced graphene oxide (ZF-rGO) nanocomposites with enhanced magnetic properties were successfully prepared using graphene oxide (GO), Fe3+, Zn2+ and ethylene glycol (EG) via a one-pot solvothermal method and the adsorption property was evaluated by the adsorption amount of methylene blue (MB) solution on the samples. The results indicate the as-prepared materials possess good adsorption and cycling properties for MB molecules. The dominated reason is mainly ascribed to the π-π stacking between dye molecules and rGO. Simultaneously, the adsorption kinetic behavior of MB molecules is also discussed and follows pseudo-second-order kinetic very well. Particularly, the introduction of Fe2+ enhances the magnetic property of ZF component in ZF-rGO composite by the reducing action of EG, which ensures the outstanding magnetic separability of the ZF-rGO materials as the adsorbent. Thus, the as-prepared nanocomposite material can be a potential excellent absorbent for removing dye pollutants.
