Adsorption performance of CuFe2O4/rGO nanocomposites towards organic dye

A facile and efficient approach was employed to synthesize CuFe2O4/rGO (reduced graphene oxide) nanocomposites. The morphology, crystal structure and properties of the prepared CuFe2O4/rGO nanocomposites were characterized by transmission electron microscopy, energy-dispersive X-ray spectroscopy, powder X-ray diffraction and thermo-gravimetric analysis. The CuFe2O4/rGO nanocomposites were applied as adsorbents to study their adsorption performance for Congo red. The adsorption capacity and recyclability, adsorption dynamics and adsorption models were investigated. The results show that the CuFe2O4/rGO nanocomposites are efficient and recyclable adsorbents.
