Abstract
Capillary zone electrophoresis (CZE) was used to determine the pKa values of six environmentally and metabolically important PAH metabolites. The pKa values obtained from CZE were close to the pKa values reported in the literature which were obtained by spectroscopy. In this work, it was found that CZE is very suitable for the determination of the pKa values of the weakly acidic, large ring PAH metabolites. A pKa value acquired for one of the model compounds by spectrometry gave supporting evidence for the reliability of CZE in obtaining pKa values for relatively large molecular weight hydroxyl compounds.
