摘　　要：挥发酚的检测是近年来废水监测中的必测项目。挥发性酚类的分析方法很多,在生活废水挥发酚的浓度较低,目前普遍采用4-氨基安替比林氯仿反萃取法,但该方法在实际操作中仍存在着准确度不易把握,结果易于偏低等许多问题。因此,本文对影响该方法的几种主要因素进行探讨,提高了该项目的准确度,节省了操作时间。For routine monitoring of waste water, the determination of volatile phenol was a necessary item in recent years. There were many methods of analysis of volatile phenols. 4 - AAP anti - chloroform extraction method of measure volatile phenols was widely used in the determination of low concentration of volatile phenol at present. But this method still remained to be improved in practice. Some influencing factors during the method were discussed, and the operation accuracy was improved and time was shorten.
