摘　　要：建立了用气相色谱法测定废气中丁酮的方法。废气中丁酮活性炭吸附,二硫化碳解吸,NNOWAX毛细管柱分离,直接进样分析,氢火焰离子化检测器检测,时间定性,峰面积定量,其丁酮回收率为90.2%～104.3%,当采样体积为30L,丁酮最低检出质量浓度为0.001mg/m3。本方法前处理简便,分离度好干扰少,分析灵敏度高,有机试剂使用量少,满足环境分析要求。Establishment of a gas chromatographic method for determination of butanone method in waste gas. Methyl ethyl ketone in the waste gas adsorption of activated carbon, carbon disulfide desorption, NNOWAX separated by capillary column, direct injection analysis, hydrogen flame ionization detector, time is qualitative, quantitative peak area, the ketone recovery rate was 90.2% - 104.3%, when the sampling volume 30L, methyl ethyl ketone, the minimum detectable concentration was 0. 001 mg/ m^3. This method is easy pretreatment, separation of good little interference, high analysis sensitivity, organic reagents used less, to meet the requirements of environmental analysis.
