摘要：

An analytical procedure is developed for the determination of priority pollutant polynuclear aromatic hydrocarbons (PAHs) in raw sewage, primary effluent, and primary sludge from municipal waste water treatment works. Extraction of sample with cyclohexane is followed by a two-step column chromatographic cleanup employing aluminum oxide and silica gel, with final determination by gas chromatography/mass spectrometry (GC/MS). The procedure and its individual steps are subjected to detailed method validation (preliminary analytical quality control). Efficiency in terms of the magnitude and repeatability of determined recovery is shown to be high, attaining an overall mean recovery of 84% with no significant influence of determined concentration or of sample matrix.
