FIELD: analytical chemistry.
SUBSTANCE: invention relates to analytical chemistry. A method for preparing samples of acid-type chemical reagents for the determination of organochlorine compounds includes taking a sample of a chemical reagent, obtaining an analyzed sample for subsequent determination of the content of organochlorine compounds, while the selected test sample of a chemical reagent is placed in a chromatographic column and passed through a sorbent layer, the column is washed with an eluent, in which is used as a hydrocarbon solvent, the resulting eluate is successively washed with an equal volume of an alkali solution and three times with equal volumes of deionized water, the eluate is separated from deionized water and an analyzed sample is obtained for subsequent determination of the content of organochlorine compounds.
EFFECT: simplification of the method, increasing the accuracy and reliability of determining the content of organochlorine compounds in acid-type chemical reagents.
