FIELD: chemistry.
SUBSTANCE: method involves oxidation of humic acids and detection of their oxidation products, wherein the oxidising agent used is molecular bromine taken in amount of 0.05-0.25% of the weight of the water sample, and detection is carried out using capillary gas chromatography.
EFFECT: increased sensitivity and reliability of analysis.
