气相色谱法测定废水中酚的研究

气相色谱法测定工业废水的酚是环境分析工作者重要研究的课题之一,用这种方法测定苯酚、邻甲酚、间甲酚、对甲酚4种挥发酚及二元酚、三元酚,测得其回收率在86.0%～98.1%之间,相对标准偏差在4.5%～7.3%之间。文章对工业废水中酚的测定进行了分析。

Research on Gas Chromatography Determining Phenol in Wastewater

Using gas chromatography determining phenol in industrial wastewater is one of the important research topics for the workers of environment analysis.Using this method determines 4 binary phenol including phenol,o-cresol,m-cresol,p-cresol,diphenol and triatomic phenol.Through the determination,we can obtain that the recovery is between 86.0% and 98.1%,and relative standard deviation is between 4.5% and 7.3%.The article analyzes on the determination of phenol in industrial wastewater.
