Abstract
Carboxymethyl cellulose (CMC) is grafted on multiwalled carbon nanotubes (MWCNT) by using plasma techniques. The CMC grafted MWCNT (MWCNT-g-CMC) is characterized by using Fourier transform infrared spectra (FT-IR), Raman spectra, powder X-ray diffraction (XRD), thermogravimetric analysis (TGA)−differential thermal analysis (DTA), scanning electron microscopy (SEM), and N2-BET methods in detail. The application of MWCNT-g-CMC in the removal of UO22+ from aqueous solution is investigated. MWCNT-g-CMC has much higher sorption ability in the removal of UO22+ than raw MWCNT. The MWCNT-g-CMC is a suitable material in the preconcentration and solidification of heavy metal ions from large volume of aqueous solutions.Keywords
