摘要
对４─氨基安替比林氯仿萃取比色法测定水中的挥发酚，如何更好地降低空白值作了介绍，阐述了对显色剂不同的提纯方法，并对各种方法作了合理的分析、评价．找出了一种既能降低测定空白值，又不影响方法的灵敏度，并保证分析结果精密度和准确度的方法．
he determination of volatile phenol and how to decrease the background wes reported. meanwhile, the different purifing ways of 4-amino-antipyrine wrer introduced and discussed. A rational purifing way of 4-amono -antipyrine has been given, which has lower background, high sensitivity to ensure precision and accuracy high enough.
