生活饮用水中三氯乙烯检测新方法的研究

Methodology for detection of TCE in drinking water

目的建立饮用水中三氯乙烯的新测定方法。方法采用氢火焰离子化检测器(FID)-顶空气相色谱法(HGC)测定三氯乙烯。结果结果显示相关系数为0.9999,检出限为2.86μg/L,加标回收率为95.7%～98.4%。结论本法具有操作简便、快速,灵敏度高,方法线性好,结果准确可靠等优点,值得推广。

Objective To determinate triehloroethylene in drinking water. Methods To determinate trichloroethylene by used the method of hydrogen flame ion detection-headspace gas chromatography. Results The correlation coefficient of this method was 0.9999. The detection limit was 2.86μg/L. The recovery rates added with standard were 95.7%-98.4%. Conclusion The advantages of this method is simple, rapid, high sensitivity, linear, accurate and reliable.
