Abstract

[Objective] To develop a method of determining volatile chlorinated hydrocarbons in drinking water by purge and trap gas chromatography mass spectrometry.[Methods] The experimental conditions of purge and trap,and gas chromatography were optimized.Water samples were determined and analyzed [Results] The minimum detection limit of this method was 0.06～0.24 μg/L,with precision of RSD3%,and recovery of standard addition of 92%～106%.[Conclusion] This method is accurate,and suitable for analysis of multicomponent trace halohydrocarbon in drinking water.
