采用动态顶空气相色谱FID法测定水中乙醛、丙酮、甲醇、丙烯醛、丙烯腈、乙腈、吡啶等7种极性水溶性有机物，通过优化动态顶空条件，使该方法在0．157 mg/L～7．92 mg/L之间线性良好。方法检出限在0．008 mg/L～0．048 mg/L之间，空白水样的加标回收率为103％～111％，RSD为5．4％～8．7％。用该方法测定某制药企业排口污水和地表水，只有污水中甲醇、乙腈、吡啶有响应值。
採用動態頂空氣相色譜FID法測定水中乙醛、丙酮、甲醇、丙烯醛、丙烯腈、乙腈、吡啶等7種極性水溶性有機物，通過優化動態頂空條件，使該方法在0．157 mg/L～7．92 mg/L之間線性良好。方法檢齣限在0．008 mg/L～0．048 mg/L之間，空白水樣的加標迴收率為103％～111％，RSD為5．4％～8．7％。用該方法測定某製藥企業排口汙水和地錶水，隻有汙水中甲醇、乙腈、吡啶有響應值。

Dynamic headspace gas chromatography equipped with FID was applied to test the acetaldehyde, acetone, methanol, acrolein, acrylonitrile, acetonitrile and pyridin in water.The dynamic headspace conditions were optimized.The method had good linearity from 0.152 mg/L to 7.92 mg/L.The method detection limits were between 0.008 mg/L and 0.048 mg/L.The spiked recovery in blank water ranged from 103%to 111%, with the RSDs 5 .4%~8 .7%.This method was used to test wastwater of some pharmaceutical enterprise and surface water.Only methanol, acetonitrile and pyridin were detected in wastwater.
