中文摘要:
      利用吹扫捕集气相色谱-质谱法检测地下水中挥发性有机污染物,建立适用于全国地下水调查中卤代烃、苯系物、氯苯等25种必检组分测定的分析流程,同时增加分析过程的质量控制与质量管理。各组分标准曲线线性方程相关系数均在0.9995以上,方法检测限为0.1~0.4 μg/L。标准添加样品测定值相对标准偏差为1.73% ~5.53%(n=7),回收率为88.8% ~112.0%。建立的分析方法检测限低、精密度好、方法简便、准确,适用于地下水调查等大批量挥发性有机污染物的分析。
英文摘要:
      A method for the determination of 25 volatile organic compounds, including halohydrocarbons, benzene series, chlorobenzene and etc., by purge and trap-GC/MS in groundwater samples from China Groundwater Survey Project was developed. The detection limits of the method for VOCs were in the range of 0.1~0.4 μg/L and the recoveries were between 88.8%~112.0% with precision of 1.73%~5.53% (n=7). The correlation coefficients of the calibration curve equations for the analytes were better than 0.9995. A quality control procedure for semi-volatile organic compound analysis in groundwater was also proposed. The method provides the advantages of high sensitivity, high accuracy and precision, simple operation and is suitable for batch analysis.
