Solid phase extraction(SPE) technology was employed in the analysis of Di-butyl phthalate and Di-2-ethylhexyl phthalate (DBP and DEHP) in aquatic products by GC. DBP and DEHP were extracted with acetonitrile and on C_(18) cartridge before analysis was performed by electron capture detection - capillary gas chromatography. The detection limits were DBP0.7mg/l and DEHP0.2mg/l, respectively. The recoveries were 76.0%108.6%. The RSDs were 2.82%9.39%. The method provides a rapid determination of DBP and DEHP (1mg/l10mg/l) in aquatic products.
