FIELD: carbon materials. ^ SUBSTANCE: invention provides a three-step method for modifying industrial activated carbon. In the first step, activated carbon is treated for 12 -24 h with epsilon-caprolactam aqueous solution under static conditions. Then, activated carbon is filtered, dried, and heated at 250°C in air atmosphere. Finally, it is subjected to carbonization by heating to 900°C in inert gas (argon or nitrogen) flow. ^ EFFECT: increased sorption capacity relative to organic compounds and heavy metal ions. ^ 2 tbl, 2 ex |
