摘要:
建立了柱前衍生化-固相萃取-气相色谱法快速测定水样中五氯酚的方法。结果表明,目标化合物在气相色谱条件下可以实现很好的基线分离,五氯酚在质量浓度0.05~50.0 μg/L 范围内呈现良好的线性关系,相关系数r=0.998,方法检出限为0.006 μg/L,测定下限为0.024 μg/L,相对标准偏差均<10%。该方法具有较高的精密度和准确度,且简便高效,适用于水体中五氯酚的测定。

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.
