The study on preparation of sorbents based on carbon residue of tire pyrolysis is presented in the article. As a part of the study, carbon residue was refined to improve its processing characteristics. It is found that refining resulted in twofold total pore volume increase. Also, the iodine adsorption value depends on the time of reaction. Adsorption capacity increases as the time of interaction with iodine solution increases. Refined 0,2 mm size grade carbon black has the best adsorption value. When an aqueous solution of 1 g/dm3 phenol was passed through the filter, the purification efficiency was about 35%; when phenol concentration was 0,1 g/dm3, purification efficiency amounted to about 85%. The filter being re-used; the absorption capacity is reduced to 50%. The absorption capacity decreases due to the sorbing micro-pore bridging. Phosphoric acid activation of spent adsorbent provides for the restoration of its sorption properties and allows its re-use.
