摘要：

Column liquid chromatography with fluorescence and diode-array UV detection has been used for the trace-level determination of sixteen EPA-priority polycyclic aromatic hydrocarbons. The procedure involves on-line micelle-mediated preconcentration on selective sorbents. Using Brij-35 as the surfactant, unwanted adsorption of the analytes on inner walls or surfaces is prevented. The system has been used for the analysis of surface water samples, and detection limits typically are at the low- to sub-ng/l level. The system is robust and repeatability is excellent.
