４－氨基安替比林（简称４－ＡＡＰ）萃取光度法测酚是灵敏度很高的标准分析方法。该方法要求使用无酚水。本文经过实验分析提出以蒸馏水代替无酚水测定地面水中挥发酚，结果表明，本方法检出限为０．０１７ｍｇ／ｌ，具有较高的精密度和准确度。本法省略了制备无酚水的程序，从而使实验分析得到简化。
4-aminoantipyrine (4-AAP) extraction spectrophotometric determination of phenol is a high sensitivity standard analytical method. This method requires the use of phenol-free water. The experimental results show that the detection limit of this method is 0.017mg / l with high precision and accuracy. This procedure omits the procedure for preparing phenol-free water, which simplifies the experimental analysis.
