Activated carbon is a porous substance that is obtained from various carbon-containing materials of organic origin: charcoal (brands of activated carbon BAU-A, OU-A, DAK, etc.), coal coke (brands of activated carbon AG-3, AG-5, AR etc.), petroleum coke, coconut shells and other materials. It contains a huge number of pores and therefore has a very large specific surface area per unit mass, as a result of which it has a high adsorption capacity. Depending on the manufacturing technology, 1 gram of activated carbon can have a surface area of 500 to 2200 m². It was first synthesized by Nikolai Dmitrievich Zelinsky (1915), used by him in gas masks as a universal means of chemical protection, and later as a heterogeneous catalyst. Used in medicine and industry for purification, separation and extraction of various substances. Time of action after taking 20-30 minutes.
