FIELD: technological processes.
SUBSTANCE: invention relates to the field of production of absorption materials. Method to modify natural absorbents is proposed. Method includes addition of multi-wall carbon nanotubes in the amount of 0.1-1.0 wt % into suspension containing finely dispersed zeolyte or diatomite in 0.5% solution of aluminium sulfate. Ultrasonic treatment of the suspension is carried out, solution of ammonia hydroxide is added to the suspension to pH 7-8, fluid is separated, and thermal treatment of the produced absorbent is carried out at 120°C.
EFFECT: invention provides for production of absorbent characterized by extent of oil products and metal cations from water up to 99,4%.
