FIELD: chemistry.
SUBSTANCE: invention can be used in obtaining adsorbents in substances for smoking and filters for tobacco smoke trapping. Granules of microporous activated coal of vegetable origin are submerged into solution of alkali earth or alkali metal, shaken, filtered with the following drying of filtered coal. Microporous coal, processed with salt, can be activated with vapour, for instance, in argon, for 1-10 h. Obtained coal has volume of micropores at least 0.4 cm3/g and volume of mesopores at least 0.3 cm3/g.
EFFECT: invention provides improved capability of coal to filter tobacco smoke.
