CHROMATOGRAPHIC DETERMINATION OF OIL PRODUCTS IN NATURAL AND MINERAL WATERS

摘要

For determination of oil products in natural and mineral waters we proposed a method including extraction of hydrocarbons with hexane, sorption purification of the concentrate, luminescent detection, gas-chromatographic identification, and detection. The method makes it possible to detect oil products at the MAC level and establish their variety type (gasoline, kerosene, ligroin, diesel fuel, fuel oil, and lubricating oil). We proposed an internal standard for analysis of mineral waters of Ukraine's oil-gas-bearing regions. The method was tested when determining hydrocarbons of oil having anthropogenic origin and also when investigating curative-table waters of the Ukrainian Carpathian mountains and Transcarpathian region.
