FIELD: analytical methods. SUBSTANCE: in a method wherein sample is passed through chromatographic column filled with polymer adsorbent and eluate is colorimetrically detected, polymer adsorbent is Polysorb C treated with mixture of chloroform and dicyclohexyl-18-crown-6 at their weight ratio (42-48):(58-62). Such procedure allows one to increase selectivity coefficient when determining phenol and guaiacol in an aqueous solution (2.3 against 1.2 as previously) and to reduce analysis time (1 h instead of 3 h). EFFECT: improved and accelerated analytical procedure. 1 tbl, 7 ex
