Abstract

Abstract
Nanocomposites of Ferberite-graphene oxide were prepared via a simple sonication method. The structure, surface morphology and chemical composition were characterized by Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Raman, energy dispersive X-ray spectrometer (EDS), transmission electron microscopy (TEM), selected area electron diffraction (SAED). XRD results confirm the interaction of Ferberite with graphene oxide. A fast adsorption of the uranium from aqueous solution was observed with an efficiency of 90.6 % within 30 min. the adsorption of uranium ions could be well-described by the Langmuir, Freundlich isotherms and pseudo-second kinetic models.
