The simple method for preparation of nanocomposites of graphene oxide or carboxylated graphene oxide on polystyrene matrix and graphene oxide on PA66 matrix were developed and structures of nanocomposites were characterized by X-ray diffraction, infrared spectroscopy, Raman spectroscopy, high-resolution scanning electron microscopy, transmission electron microscopy and scanning transmission electron microscopy. The nanocomposites were investigated for radiostrontium removal from aqueous solutions. The Sr(II) sorption was dependent on pH and ionic strength at pH < 7. The Sr(II) equilibrium data were fitted by Freundlich and Langmuir models. The nanocomposites prepared were evaluated as suitable for the radiostrontium removal from contaminated wastewater.
