摘要
A drop version of the extraction preconcentration of organochlorine and aromatic impurities from water is developed. One microliter of carbon tetrachloride is used as an extractant. The distribution and preconcentration coefficients of impurities are determined. Factors affecting the stability of the extractant drop are studied. The limits for the gas-chromatographic detection of the impurities with their drop preconcentration are (2-5) x 10(-5) mg/L.
