| Abstract: | A new method of using micro-extraction technology to measure the halohydrocarbon in tap water was reported.Experiment showed that the optimum condition was 110 ℃ column temperature,140 ℃ detector temperature and larger than 35 ml/min flux of huff(total flux larger than 55 ml/min).The method of liquid-liquid extraction-GC-ECD was used to measure the halohydrocarbon in tap water and the proportion between organic facies and water sample was 1∶50.The minimum detection limit was about 1 μg/L and variation coefficient was smaller than 10 %. |
