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. 0μg/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. 006μg/L,测定下限为0. 024μg/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。
An analytical method fl）r the rapid determination of pentachlorophenol in water samples by pre column derivatization solid phase extraction and gas rhromatography was established. The results show that the target compounds （-an 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.
