| Abstract: |
| An analytical method for the rapid determination of pentachlorophenol in water samples by pre column derivatization solid phase extraction and gas chromatography was established. The results show that the target compounds can be well separated by gas chromatography. The Pentachlorophenol has a good linear relationship in the range of mass concentration of 0.05~50.0 μg/L, the correlation coefficient r=0.998.The detection limit is 0.006 μg/L and the limit of quantitation is 0.024 μg/L. The relative standard deviations were all less than 10%.The method has high precision and accuracy, and is simple and efficient. It is suitable for the determination of pentachlorophenol in the water. |
