Determination of volatile halogenated hydrocarbons in drinking water by automatic headspace capillary gas chromatography

[Objective]To establish a method for rapid determination of multi-mixture volatile halogenated hydrocarbons in drinking water with headspace capillary gas chromatography.[Methods]The experimental conditions of headspace,such as the balance temperature,balance time,gas liquid phase ratio and the analytical conditions of GC were optimized.Volatile halogenated hydrocarbons in drinking water were determined by headspace gas chromatography.[Results]The recovery of 9 kinds volatile halogenated hydrocarbons were between of 89.5%～117.2%.the relative standard deviation(RSD) was 1.7%～6.3%.The lowest determination limit was 0.01～2.80 μg/L.[Conclusion]The method is simple,rapid,sensitive and accurate.Therefore,it is suitable for analysis of multi-mixture volatile halogenated hydrocarbons in drinking water.
