Abstract
The use of the solid-phase extraction technique for the rapid sample preparation of organochlorine pesticides is described. Samples were simultaneously extracted, cleaned, and fractionated by the solid-phase extraction method and a further separation and determination of extracted fractions was carried out by gas chromatography with either an electron capture or a Hall electrolytic conductivity detector. The percent recovery of the extracted seven pesticides was compared to that of the conventional liquid-liquid extraction method. The analytical figures of merit., chromatograms, and statistic data are reported. The application of this method was demonstrated by a real fish sample determination with mass spectra for confirmation of Kepone detection.
