摘要：

The on-line isolation and trace enrichment of the pesticides simazine, atrazine, carbaryl, propanil, linuron and fenamiphos from different waters is described. The Pesticides were spiked at 0.05-0.5 mu g L(-1) in mineral, tap, ground and sea water and were preconcentrated using on-line solid-phase extraction onto a C-18 precolumn followed by column liquid chromatography-diode array detection (LC-DAD). The salting-out effect was studied in order to improve the breakthrough volumes. Detection limits lower than 0.1 mu g L(-1) were obtained for all pesticides studied.
