Abstract

Abstract: Nano-composites were synthesized by the reaction of waste polystyrene (PS) and KMnO4 . The structure of the composite was controlled by the solvent/non-solvent system and the concentration of KMnO4 . The FTIR spectra indicated the functionalization of PS and the attachment of NMO with the polymer chains. The maximum adsorption capacities ( q max ) were 10, 000 and 5000 Bq g −1, for U and Th respectively. Different but controllable sorption/desorption behaviours were noted between Th and U, which could be promising in the separation of Th and U from their mixture. Highlights: Styrofoam-nano manganese oxide based composite was successfully prepared. The composite was used for U and Th removal from solution. The structure was controlled by solvent/non-solvent system and [KMnO4]. The PS-NMO could be promising in the separation of Th and U from their mixture.
