| 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 - 0.24μg/L, with precision of RSD 〈 3% , and recovery of standard addition of 92% - 106%. Conclusion] This method is accurate, and suitable for analysis of muhicomponent trace halohydrocarbon in drinking water. |
