FIELD: chemistry.
SUBSTANCE: described is a method of determining methylphenols in aqueous media, involving chemical modification thereof into acetates, extraction concentration and gas-chromatographic detection, where at the first chemical modification step, the modifier reactant used is iodine in amount of 0.005-0.015% in the presence of ammonium acetate and ammonia in amount of 0.3-1.0% of the weight of the water sample; acylation is carried out in a medium of an organic solvent, and an electron capture detector is used for detection.
EFFECT: high sensitivity of analysis.
