FIELD: ecology; hydrochemistry; analytical chemistry; methods of extraction of the volatile organic substances from the water medium.
SUBSTANCE: the invention is pertaining to the field of ecology, hydrochemistry, analytical chemistry and may be used for extraction of the organic compounds from the water mediums, in particular, from the mineral waters including sulfide mineral waters. For realization of the method of extraction of the volatile organic substances from the water medium into the organic dissolvent conduct the joint condensation of the extracted substance produced as a result of distillery and the vapor of the dissolvent. For production of the joint condensate they gate the vapor-shaped dissolvent through the water sample or preliminary add it into the water sample with the subsequent distillation. The organic dissolvent is chosen from the following row: ethanol, acetonitrile, acetone, hexane. The method ensures the single-stage extraction of the dissolved organic substances into the dissolvents, the unlimited their mixing with the water, reduction of the thermal action on the researched sample, the increase of the extraction ratio.
EFFECT: the invention ensures the single-stage extraction of the dissolved organic substances into the dissolvents, their unlimited mixing with the water, the reduced the thermal action on the researched sample, the increased extraction ratio.
