4－AAP萃取光度法以蒸馏水代替无酚水测定地面水中挥发酚

Testing Volatile Phenol of Surface Water by4-Amino Antipyine Spectrophotometry with Distilled Water Instead of None-phenol Water

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。

Testing phenol by 4-amino antiyrine spectrophotometry is a standardized analysis means with higher sensitivity which none-phenol water is required.using distilled water instead of none-phenol water to test surface water is put forward through a series of laboratory tests.This method is simple and highly sensitive.The detection limit is 0.0017 mg/l.
