Trace levels of phenol and methylphenols (cresols) in aqueous samples were determined by continuous liquid-liquid extraction and normal-phase high-performance liquid chromatography with UV-fluorescence detection. The recovery of phenol from water at a concentration of 1.6 micrograms l-1 was 70 +/- 6%. The method successfully measured traces of phenol and cresols extracted from rainwater without further clean-up. The average reproducibility of the method for rain samples was +/- 16%. The results compared well with those obtained by high-resolution gas chromatography-mass spectrometry.
通过连续液-液萃取和带有紫外-荧光检测的正相高效液相色谱法测定水样中痕量的苯酚和甲基苯酚（甲酚）。在浓度为1.6微克/升的水中，苯酚的回收率为70±6%。该方法成功测定了从雨水中萃取的痕量苯酚和甲酚，无需进一步净化。该方法对雨水样品的平均重现性为±16%。结果与通过高分辨率气相色谱-质谱法获得的结果比较吻合。
