FIELD: carbon adsorbents production.

SUBSTANCE: invention relates to the field of obtaining carbon adsorbents for the adsorption of organic substances, heavy metals and microflora from water and aqueous solutions based on graphite thermal soot containing С₆₀fullerene. Also, the adsorbent is suitable for passive adsorption of organic substances from the gas-air mixture of the soil. The method for obtaining a carbon adsorbent includes treating a carbon material with a solution containing fullerene and a stabilizer that maintains fullerene in solution in a dispersed form, at a mass ratio of fullerene:stabilizer equal to 1:440000 for o-xylene, and fullerene:stabilizer 1:435000 for toluene. As a carbon material, graphitized thermal carbon black is used, for the treatment of which 104 g of a 1N NaOH solution containing fullerene in an amount of not more than 0.0002 g is used, to which a stabilizer selected from o-xylene and toluene is preliminarily added.

EFFECT: method makes it possible to modify the surface of a carbon material for passive adsorption of С₅-С₂₀ hydrocarbons with an aqueous solution containing С₆₀ fullerene and a stabilizer selected from the group of aromatic compounds.
