Linear β-cyclodextrin polymer functionalized multiwalled carbon nanotubes (MWCNTs-CDP) were synthesized and employed as a novel nanoadsorbent to remove uranyl ions in wastewater solutions. The characterization of MWCNTs-CDP, with Fourier transform infrared (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET), suggested that the CDP was successfully modified on the MWCNTs surfaces. The removal efficiency of uranyl ions in aqueous solution by MWCNTs-CDP was investigated via varying various experi...
