Sorption Preconcentration and Determination of o-Xylene and Polynuclear Aromatic Hydrocarbons in Atmospheric Precipitates by Gas Chromatograpgy–Mass Spectrometry

The conditions of the sorption concentration of o -xylene and polynuclear aromatic hydrocarbons ( PAHs ) on hypercrosslinked polystyrene in the dynamic mode are developed. A procedure is proposed for the determination of o -xylene and PAHs in thawed snow, based on the sorption preconcentration of th...

Description
Summary:The conditions of the sorption concentration of o -xylene and polynuclear aromatic hydrocarbons ( PAHs ) on hypercrosslinked polystyrene in the dynamic mode are developed. A procedure is proposed for the determination of o -xylene and PAHs in thawed snow, based on the sorption preconcentration of these compounds and their further determination by gas chromatography–mass spectrometry. Samples of thawed snow taken in the park of Moscow State University are analyzed.
