Abstract
Polymer native cellulose matrix modification was made by impregnation method using carbon nanosized particles. Kinetics and equilibrium of adsorption of Cu(II), Ni(II) and Cd(II) ions on native cellulose and composite materials are studied. It is determined, that modifying of cellulose effectively increases adsorption capacity of an adsorbent for heavy metal ions and reduces the half adsorption period. It was suggested according to IR-spectroscopy data that in the composite material between the polymer and the fullerene there realized Van der Waals interaction.
Keywords: adsorption, cellulose materials, fullerene, metal ions
