Abstract

The ion-pair chromatographic behaviour of a naphthol and some sulpho-substituted naphthols and nitroso-naphthols is studied. Formation of the ion-pair compounds is done either by pre-extraction or during elution with long-chained quaternary alkyl- or alkylarylammonium salts. Identification is based in UV/VIS absorption using a diode array detector at 229, 240, 254 or 280 nm. Special emphasis is placed on the column material, the positions of the substituents in the naphthols and the organic ion-pairing agents in the eluent.
