| Abstract: |
| 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 parameters were optimized.The impact factors of extraction efficiency such as fiber type,extraction temperature,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. |
