建立了固相微萃取/气相色谱法（ SPME/GC）同时测定水中13种氯代苯胺的方法。优化了GC测定条件，研究了纤维头类型、萃取温度、萃取时间、萃取pH值、离子强度和解吸时间对萃取效果的影响。在优化条件下，各目标组分在一定浓度范围内线性关系良好，检出限为0.05~0.34μg/L。用于实际水样分析，加标回收率为76.0％~121％，相对标准偏差为0.3％~17.2％。方法可用于水体中13种氯代苯胺的快速痕量分析。

A gas chromatographic method coupled with solid phase microextraction( SPME/GC)was developed for the determination of 13 chlorinated anilines residues in water. The instrumental param-eters were optimized. The impact factors of extraction efficiency such as fiber type,extraction tem-perature,absorption time,pH value,ionic strength and desorption time were also studied. Under the optimized conditions,the calibration curves were linear in certain concentrations. The detection limits were 0. 05-0. 34 μg/L. The spiked recoveries of analytes in actual sample ranged from 76. 0%to 121% with relative standard deviations of 0. 3% -17. 2%. The proposed method is suitable for the quick determination of trace level of 13 chlorinated anilines residues in water.
