| Abstract: | A method for the determination of 11 chlorobenzene compounds in water had been established by petroleum-ether extraction,capillary gas chromatography with electron capture detector.The whole procedure was just 25 min,and the minimum detection limits reach 0.001~0.01 μg？L-1 and were lower than those of GB/T5750.8-2006.The recoveries of every compounds was between 80 % and 105 %.The relative standard deviation ranged from 1.5 % to 4.5 %.The method can been used to the determination of chlorobenzene compounds in water. |
