| 英文摘要 | a novel poly(phthalazine ether sulfone ketone) (ppesk) film prepared by immersion precipitation technique was coated on stir bars for sorptive extraction. scanning electron micrographs showed that the coating has a denser porous surface (about 1 mu m in thickness) with a sponge-like sublayer, and the thickness of the coating was 250 mu m. the ppesk coated stir bar has high thermostability (290 degrees c) and long lifetime (50 times). the extraction properties of this stir bar were evaluated for the extraction of both polar and semi-polar analytes, including organochlorine compounds and organophosphorus pesticides. the ppesk stir bar was proved to show higher affinity towards polar compounds than that of pdms coated stir bar and higher sample load compared with corresponding ppesk fiber. it was applied to the determination of organochlorine compounds in seawater samples and organophosphorus pesticides in juices by gas chromatographic analysis. the effect of sample matrix was evaluated at optimized condition of extraction temperature, extraction time and salt concentration. limits of detection were in the range of 0.05-2.53 ng l-1 for organochlorine compounds in seawater samples using electron capture detector (ecd), with precisions of less than 11% rsd. limits of detection for organophosphorus pesticides were in the range of 0.17-2.25 ng l-1 and 2.47-10.3 ng l-1 in grape and peach juice, respectively, using thermionic specified detector (tsd), with precisions of less than 12% rsd and 20% rsd, respectively.
