建立一种测定邻甲酚、间甲酚和对甲酚的毛细管气相色谱分析方法. 邻甲酚和间甲酚的峰面积与浓度在2~200g/L范围内呈线性关系,相对标准偏差分别为1. 84%、1. 67%;对甲酚在2~210g/L范围内呈线性关系,相对标准偏差为1. 63%,测定回收率均在96. 4%~103. 8%.
建立一種測定鄰甲酚、間甲酚和對甲酚的毛細管氣相色譜分析方法. 鄰甲酚和間甲酚的峰麵積與濃度在2~200g/L範圍內呈線性關繫,相對標準偏差分彆為1. 84%、1. 67%;對甲酚在2~210g/L範圍內呈線性關繫,相對標準偏差為1. 63%,測定迴收率均在96. 4%~103. 8%.

This paper establishes a separation and determination method for o-cresol,m-cresol and p-cresol with capillary gas chromatography. The peak area and concentration of o-cresol and m-cre-sol have linear relationship in the range of 2~200g/L,and the relative standard deviation is respec-tively 1. 84% and 1. 67%;the same of p-cresol has linear relationship in the range of 2~200g/L, and the relative standard deviation is 1 . 63%. The determined recovery rate of them are all between 96. 4%~103. 8%.
