| 摘 要： | 建立了顶空气相色谱-质谱检测地表水中四氯乙烯残留量的方法，全扫描离子监测模式检测，方法的检出限为1．2μg/L，在10--200μg／L范围内呈现良好的线性关系，相关系数为0．9992，在20，30和50μg／L3个添加水平下，四氯乙烯的加标回收率在97．8％-101．7％之间，相对标准偏差（RsD）在1．65％-3．61％之间，该方法灵敏度高，分离效果良好，能有效地消除复杂基质带来的干扰，可以作为地表水中四氯乙烯残留量的检测和确证方法。

| Abstract: | We developeed the method for the determination of tetrachloroethylene in surface water using the gas chromatography-mass spectrometry （GC-MS）. the total scan ion mode is used to monitor the object, good relativeity （r〉0.9992） was obtained when the linear range was between 10-200 μg/L. The recoveries of tetrachloreethylene were between 97.8%-101.7%. The relative standard deviations were within 1.65%- 3.61%. The determination limit is less than 1.2μg/L. The advantage of thi smethod is simple, rapid and sensitive. |
