FIELD: chemistry.
SUBSTANCE: invention refers to drinking, natural and waste water, precipitation sanitary-hygienic control and analysis for phenol content. Method includes chemical phenol modification in 2,4,6-tribromphenol, extraction concentration of 2,4,6- tribromphenol and gas chromatography testing. Herewith chemical modification is preceded with humic acid removal on aluminium oxide from aqueous medium sample with copper sulphate in amount 0.05-0.25% of aqueous medium sample weight.
EFFECT: higher analysis reliability.
