Abstract
Ion-pair solid-phase extraction was on-line coupled to a chromatograph ic system with a PLRP-s precolumn and the results were compared with t hose obtained when C-18 sorbents are used. After optimization, the met hod was used to determine these compounds in two river waters. A sampl e of 20 ml of river water was preconcentrated with good recovery value s for all the compounds studied and detected at 220 nm with detection limits between 0.25 and 0.1 mu g l(-1). Some of the compounds were pro visionally determined by diode-array UV detection.
