In the current work, a method for obtaining an effective adsorption material (nanocomposite) through polycondensation of hexamethylenetetramine in sulfuric acid in the presence of multi-walled carbon nanotubes as texture component is proposed, and the properties of this material are studied. The elemental composition of the material was determined by energy-dispersive X-ray analysis, and the morphology was evaluated by scanning electron microscopy. Its adsorption activity was estimated towards Cu(II) ions and synthetic dyes - methylene blue (MB) and methyl orange (MO). It was established that the adsorption capacity of the studied material for the dyes is 1,255 and 801 mg g−1 (for MB and MO, respectively), whereas for Cu(II) ions, it is 24.5 mg g−1. Besides, the kinetics of the adsorption of all those species was studied, thereby making it possible to determine the expediency of using the developed nanocomposite for purification of aqueous solutions.
