Abstract： In this paper， chlorothalonil and deltamethrin in drinking water were extracted by liquid-liquid extraction and solid phase extraction. After vacuum concentration， components were separated by HP-5 capillary column and detected by electron capture detector（ECD）.After comparing the two extraction methods in the article， solid-phase extraction was used as the pretreatment method.

Key words： chlorothalonil； deltamethrin； liquid-liquid extraction； solid phase extraction； gas chromatography
