摘要
以蒸馏水吸收环境或工业废气中的甲醇正丁醇叔戊醇,用HP-FFAP毛细管柱分离氢火焰离子化检测器检测,样品直接进气相色谱仪测定。方法最低检出质量浓度分别为甲醇0.08 mg/m^3、正丁醇0.11mg/m^3、叔戊醇0.12mg/m^3,相对标准偏差为2%-5%,加标回收率在82%-105%之间。方法简单、灵敏,分离度好、检出限低。
This method uses distilled water to absorb the carbinol, n-butyl alcohol and amylene alcohol in ambient air and exhaust gas, with which to separate with HP-FFAP capillary column and to detect with the hydrogen flame ionization detector. This sample is determined in gas chromatograph. The mass concentrations detected are carbinol 0.08 mg/m^3 , n-butyl alcohol 0.11 mg/m^3 and amylene alcohol 0.12mg/m^3 , the relative standard deviation is 2 % - 5 % , the fraction product recovery is between 82% and 105 % . The method is simple, sensitive, and with good degree of separation.
