FIELD: chemistry.
SUBSTANCE: present invention pertains to analytical chemistry of organic compounds and can be used for sanitary and epidemiological control of aqueous media. The method involves extraction of concentrated aniline, its chemical modification into 2,4,6-tribromoaniline and gas-chromatography detection of 2,4,6-tribromoaniline. Chemical modification of aniline is carried out before the extraction stage in an aqueous medium in the presence glycine in quantity of 0.1-1.0 wt % of the water sample.
EFFECT: high sensitivity, faster and simple analysis.
