摘要
在总结水环境中挥发份指标的长期监测经验基础上,对挥发酚测定过程中影响因素进行讨论,认为:必须合理选择测定方法,在水样的采集与保存、干扰物质的去除、无酚水的制备、试样预蒸馏、空白样吸光值降低等环节加以注意,实验操作严格按照规范进行,可以提高挥发酚测定结果的准确度。
Base on the experience of determination of volatile phenols in water, we talked about the influencing factor in that process, obtained thant : A rational method was must ; some process like the collection and preservation of water sample, to remove the interfering sub- stance, preparation of none aquae phenolata , the predistillation , to reduce the light absorption value of the blank must be attend ; and ex- periment operation must be as standard ; those all can raise the accuracy of the result.
