摘要：

Organophosphorus and nitrogen-containing pesticides were extracted from water using solid-phase extraction (SPE) with Sep-Pak C-18 cartridges and eluted with acetone and hexane. Different methods were evaluated to concentrate the eluates and, finally, pesticides were determined in the concentrated eluates by gas-liquid chromatography with nitrogen-phosphorus detection. Recoveries varied with the physico-chemical properties of the pesticides, being from 0% to 91%.
