摘　　要：目的:利用HS-GC技术,建立水中54种挥发性有机物的测定方法。方法:通过顶空技术对水样中挥发性有机物提取、浓缩水样,建立了水样中54种挥发性有机物的HS-GC-FID分析方法。结果:建立的方法回收率在81%～121%之间,测定精密度RSD在0.79%～14.2%之间,检出限在0.03 mg/L～0.19 mg/L之间(SIM模式)。结论:建立的方法简便、快速、灵敏、可靠性强。Objective：A method for the determination of 54 kinds of volatile organic compounds in water by gas chromatography-mass spectrometry with static headspace analysis was established.Methods：The volatile organic compounds in water samples were extracted and concentrated by static headspace.The optimum conditions were tested and discussed.Results：The limit of detection of this method was found to be 0.03 mg/L～0.19 mg/L for SIM mode.The recovery was found to be 81%～121% and its RSD to be 0.79%～14.2%.Conclusion：The method is simple,rapid,high sensitivity and high accuracy.
