title: Comparison of three derivatization ways in the separation of phenol and hydroquinone from water samples.
abstract: 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.
