| Abstract: | [Objective]To establish a method for simultaneous determination of 10 kinds of volatile halogenated compounds with headspace-gas chromatography（HS-GC） in water.[Methods]After separation of in water by CP-Sil 5CB capillarity column,10 kinds of organic compounds were detected quantitatively by electron capture detector（ECD）.[Results]The correlation coefficient of 10 kinds of organic compounds was 0.999 1-0.999 9,the average recovery was 89.3%-105%（n=6）,the RSD was 1.5%-5.5%,and the minimum detectable concentration was 0.30-20.16 μg/L.[Conclusion]The method is simple,rapid,accurate and sensitive,and it is suitable for the determination of halogenated organic compounds in water. |
