FIELD: chemical industry; production of sorbents. SUBSTANCE: natural flake or powder graphite is treated by compound having common formula MXOn, where M-H, NH4, Na, K; X - Cl, Br or J; n=1-4. Graphite thus treated is subjected to explosive decomposition which is initiated photochemically, electrochemically, mechanically, thermochemically, sonochemically or chemically. Graphite-to-compound ratio by mass is 2:1. Device for realization of this method has hermetic detachable housing, loading reservoir, receiving bin, explosive decomposition initiating unit and outlet branch pipe. Loading reservoir and receiving bin are arranged inside housing. Initiating unit may be made in form of light source, electrodes, striker with drive, supercharger, ultrasonic oscillation source, vessel containing chemical initiating agent. High-reactivity carbon mixture thus obtained contains carbon nanocrystals and particles in form of granules with fibrous surface (just as mop). EFFECT: high absorptivity relative to various agents and compounds. 14 cl, 3 dwg, 1 tbl
