Description
Summary:This paper is devoted to development of a method for modification of sorption materials based on activated carbons. The possibility of application as modifiers of carbon nanotubes is shown. Increase of absorptivity of nanomodified sorbents in the processes of removal of Co 2+ ions by 30% and Ni 2+ ions by 10–15% as compared to initial materials is noted, the static adsorption capacity of sorbents is determined. Adsorption equilibrium constants are obtained using the Freundlich and Langmuir models.
