| Abstract: | Objective]To establish the determination method of chlorobenzenes in drinking water by headspace gas chromatography. Methods]Agilent headspace gas chromatography,medium polarity capillary column（DB225,30 m×0.25 mm×0.25 μm） and temperature programming were adopted. Results]Eleven chlorobenzenes were separated well.The method detection limits were 0.005~1.3 μg/L.The linear range was 0.996~0.999.The relative standard deviation was 2%~13%,recovery ranged 70%~130%. Conclusion]This method is simple,sensitive and accurate. |
