A laboratory-scale extractor for direct supercritical fluid extraction (SFE) of liquid samples was used for removing organic pollutants from water. The extractor operates in a continuous mode, and it allows extraction of a theoretically unlimited volume of the sample. In the present study, polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) were chosen as target analytes. The method was optimized for extraction of model samples that were prepared by spiking distilled water. The method was tested by extracting real samples of river water where we have found 24 162 ng.L-1 of the target analytes. Reference data on the same samples were obtained by solid phase extraction (SPE).
