摘　　要：研究采用毛细管气相色谱法检测聚氯乙烯薄膜中残留的氯乙烯单体,并用气相色谱质谱法进行确证。样品中的氯乙烯单体采用静态顶空技术提取,利用极性毛细管气相色谱柱进行分离并结合氢火焰离子化检测器进行高灵敏度检测。氯乙烯单体在0.05～0.2 mg/L的浓度范围内有较好的线性关系,相关系数为0.999,相对标准偏差在3.1%以内,检测低限为0.5 mg/kg,该方法具有较好的检测精密度和灵敏度。A GC-hased method for the determination of vinyl chloride monomer in poly vinyl chloride is developed, Vinyl chloride monomers is extracted by headspace technology, separated in a polar capillary gas chromatography column, and detected by FID. The developed method is of the good linearity from 0.05 to 0.2 mg/L with the correlation coefficient of 0. 999. And the method is of good precision with the RSD of 3. 1% and of good sensitivity with the quantitative limit of 0.5 mg/kg.
