| 摘 要： | 通过优化顶空条件(氯化钠加入量、顶空平衡温度、顶空平衡时间),对采用顶空-气相色谱-质谱联用法测定地下水中55种挥发性有机物的方法进行探究。结果表明:该方法检出限为0.24~2.30μg/L,相对标准偏差为0.76%~13.2%,实际样品加标回收率为82.7%~119%。该方法具有较高的灵敏度、精密度和准确度,操作简便,可用于企业用地地下水中挥发性有机物的检测。

| Abstract: | In this paper,the headspace-gas chromatography-mass spectrometry method was established to determine 55 volatile organic compounds in groundwater by optimizing conditions of headspace(content of sodium chloride,equilibrium temperature,equilibrium time).The results showed that the detection limits were in the range of 0.24~2.30μg/L,the relative standard deviation was 0.76%~13.2%and the average recoveries ranged from 82.7%to 119%.This method was simple with high sensitivity,precision and accuracy and was suitable for simultaneous determination of various volatile organic compounds in groundwater of enterprise land. |
