Abstract: This article presents studies on the production of sorbents based on the carbon residue of pyrolysis of tires. During the studies refinement of the carbon residue was carried out with the aim of improving its technological characteristics. It was found that the total volume of pores as a result of refinement increased by 2 times. Also, iodine adsorption activity depends on the reaction time. Adsorption capacity increases with increasing interaction time with iodine solution. Refined carbon black, size class 0.2 mm has the best adsorption activity. When phenol water solution was passed through the filter at concentration of 1 g/dm³, the purification efficiency was about 35%, and at a concentration of 0.1 g/dm³ – about 85%. When the filter is reused, the absorption capacity is reduced to 50%. The decrease in adsorption capacity is due to the clogging of the sorbent micropores. Activation of the used adsorbent with phosphoric acid ensures a complete restoration of its adsorption properties and the possibility of its repeated use.
