摘要：

Hydroquinone and phenol were analysed in aqueous alkaline model samples using chromatographic techniques. The compounds were isolated by solid-phase extraction and determined quantitatively by capillary gas chromatography after derivatization. The effectivity of derivatization was tested in three phases of sample handling: (i) before extraction; (ii) in the extraction bed; and (iii) during elution. (C) 2004 Elsevier B.V.
