Solid-phase microextraction-gas chromatographic determination of volatile monoaromatic hydrocarbons in soil

摘要

Benzene,tolutene,ethylbenzene,three isomers of xylene,and cumene have been isolated and enriched from soil samples by a combination of water extraction at room and elevated temperature and headspace-solid-phase microextraction before their gaas chromatographic-mass spectrometric determination.
