This paper presented a method to determination of 14 kinds of nitrochlorobenzenes in water using SPME-portable GC/MS,investigating the effects such as the fiber,temperature,duration,stirring speed of extraction and releasing temperature.The optimized condition resulted from the experiment was:nitrochlorobenzenes to be extracted at 60 ℃ for 50 minutes using PDMS-DVB fiber of 65 m with a stirring speed of 200 r/min,and then the fiber was desorbed for 0.5 min in injector,and the limits of detection ranged from 1.37 to 3.57 μg/L with the fine linearity within the range of 0.01~0.50 mg/L.In addition,the spiked recoveries of practical samples were from 90.0%~115% and the relative standard deviations were between 3.93%and 6.73%.
