FIELD: chemistry.
SUBSTANCE: invention concerns production of sorbent materials for natural and industrial water and sewage treatment for removal of multicomponent impurities, such as oil and oil products, organic substances, heavy metal cations, radionuclides, ammonium cations, and other impurities. Method for obtaining carbon-containing sorbents based on natural laminar alumosilicates involves simultaneous alumosilicate calcination and processing by hydrocarbons of oil origin at 500-700°C until hydrophobic nanolayer is formed and carbon concentration in sorbent reaches 0.7-1.1%.
EFFECT: obtaining sorbents displaying ion exchange activity and high oil absorption capacity.
