    Volatile Organic Compounds Determination in Drinking Water by GC/MS Spectrometry with Puffing and Trapping Samples

      摘要
    • 摘要:
      目的 建立吹扫捕集气质联用(P&T-GC/MS)方法测定《生活饮用水卫生标准》(GB 5749-2006)中规定的12种挥发性有机物(VOCs)。
      方法 饮用水中的微量有机物经吹扫捕集提取后,HP-VOC毛细管色谱柱进行程序升温分离,质谱选择离子监测方式分析检测饮用水中12种挥发性有机物,外标法定量。
      结果 12种挥发性有机物的线性范围为0.4 μg/L~100.0 μg/L,浓度范围内的线性相关系数为0.998~0.999,检出限为0.011 μg/L~0.196 μg/L,相对标准偏差(RSD)2.37%~6.29%(n=11),加标回收率为78.0%~119.5%。
      结论 该方法适用于饮水中12种挥发性有机物的同时测定。

       

      Abstract:
      Objectives To establish a method for the determination of 12 kinds of volatile organic compounds (VOCs) in drinking water simultaneously by gas chromatography-mass spectrometry with puffing and trapping samples (P&T-GC/MS).
      Methods Twelve kinds of volatile organic compounds (VOCs) in drinking water based on the Standards for Drinking Water Quality (GB 5749-2006) were separated by HP-VOC capillary column with temperature programming, detected by gas chromatography-mass spectrometry with puffing and trapping samples, and quantified by using external standards.
      Results The linear range for VOCs was 0.4 μg/L~100.0 μg/L (r=0.998~0.999); the detection limits were 0.011 μg/L~0.196 μg/L; the relative standard deviation was 2.37%~6.29% (n = 11); and the spiked recovery were 78.0%~119.5%.
      Conclusions This method were suitable for simultaneous determination of 12 kinds of volatile organic compounds in drinking water based on the regulation in the Standards for Drinking Water Quality.
