Abstract
A method for determining sixteen PAHs, which are included in the US En vironmental Protection Agency list of priority pollutants is described . The procedure involves column liquid chromatography with fluorescenc e and UV detection and off-line concentration with solid-phase extract ion membranes. In this study, two different membranes are tested, C18 and SDB. Different steps for cleaning and conditioning the membranes t o prevent interfering peaks in the chromatogram were studied. The use of an organic solvent and Brij-35 as surfactant to prevent the analyte s from being adsorbed on inner walls or surfaces is studied. The metho d enables these compounds to be determined in tap and river water samp les at low ng 1(-1) levels.
