摘要:
采用固相萃取-高效液相色谱法测定水中7种氯酚类化合物,Waters OASIS WAX柱萃取效率最高,最佳萃取时间和洗脱时间分别为60和5min。该法的线性范围为1.0~40mg/L,检出限为0.015~0.5μg/L,精密度为0.558%~2.22%,回收率为83.2%~105%。该法适用于地表水及饮用水中氯酚类化合物的检测。

Abstract:
Seven chlorinated phenolic compounds were determined directly by solid phase extraction (SPE) and high performance liquid chromatography. Using different types of SPE columns, samples were pretreated with acidification, preconcentration, and elution before analysis. The results showed that the Waters OASIS WAX column had the highest extraction efficiency among the columns, and the best extraction time was 60 min and the best elution time was 5 min. The method had a linear regression range of 1.0~40 mg/L and a detection limit range of 0.015~0.5 μg/L. The relative standard deviations (RSD) of this method ranged from 0.558% to 2.22%, and the recovery rates ranged from 83.2% to 105%. This method was suitable for the determination of chlorinated phenolic compounds in surface water and drinking water.
