FIELD: chemistry.
SUBSTANCE: method of determining content of oil products in water is based on concentrating oil products through liquid-liquid extraction using a mixture of carbon tetrachloride and chloroform taken in ratio of 1:1 as the extraction agent, quenching fluorescence of non-hydrocarbon components with sodium nitrite and measuring fluorescence intensity.
EFFECT: faster and more reliable analysis.
