Abstract:
Objective To establish a method to determine 7 kinds of volatile halohydrocarbons in drinking water with headspace gas chromatography. Methods The water samples were heated by water bath,the water head space gas was injected into gas chromatography,separated by DB-624 capillary column and then detected by ECD detector. Results Under the optimal experimental conditions,the methods had a wide linear range,the lowest determination limits was 0.001-0.05 ?g/L,the relative standard deviation was 3.6%-8.9%,the rate of recovery was 84%-104%,the linear range of determination was 0.01-50 ?g/L. Conclusion This method is sensitive,simple,accuracy and is appllicable for determination of 7 kinds of volatile halohydrocarbons in drinking water.
