Effect of Preliminary Thermal Treatment of Active Coal on Adsorption Extraction of Anoline and Phenol
Effect of preliminary heating of active coal at a temperature of 250 <sup>о</sup>C on the porous characteristics of the adsorbent and the state of its surface was investigated. Comparative analysis of adsorption extraction of aniline and phenol from aqueous solutions with initial and preliminarily heated adsorbent samples was carried out.It was shown that thermal treatment of active coal increases the adsorption of aniline and has almost no effect on the adsorption of phenol.
