Abstract
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 μgL−1 in mineral, tap, ground and sea water and were preconcentrated using on-line solid-phase extraction onto a C18 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 μg L−1 were obtained for all pesticides studied.Keywords
