FIELD: chemical analysis.
SUBSTANCE: invention relates to a method for determining the residual amounts of fenoxycarb in the soil by high-performance liquid chromatography, including sample preparation: extraction from the soil, subsequent purification of the extract in a system of immiscible solvents: hexane, saturated sodium chloride solution, aqueous sodium bicarbonate solution and directly quantitative determination of fenoxycarb in the soil by high-performance liquid chromatography, and at the extraction stage the less toxic carbon tetrachloride is used as a solvent, and at the stage of purification of the extract, a corrugated filter was used.
EFFECT: extension of the range of methods for determining chemical substances in soil.
