| Abstract: | Objective To develop a method for the determination of halohydrocarbons in water. Methods Headspace capillary gas chromatography with ECD detective was used to simultaneously determine 10 kinds of halohydrocarbons in water. Results The recovery rates were 90. 2% - 116. 0% with the average relative standard deviations 1.75% - 5.44%. The detection limits ranged from 0. 2 μg/L to 13.0 μg/L. Conclusion The method is quick, accurate and reliable. |
