摘　　要：采用气相色谱法测定工业废气中的甲基叔丁基醚的含量。以活性炭作为采样介质,二硫化碳作为解吸溶剂。用FFAP石英毛细管柱(50m×0.32mm,0.5μm)分离,火焰离子化检测器检测。甲基叔丁基醚的质量浓度在1.48~185mg·L^(-1)范围内与其峰面积呈线性关系,检出限(4S/N)为0.3 mg·L^(-1)。对3种不同浓度水平平行测定6次,测定值的相对标准偏差在2.6%~5.7%之间。在6℃条件下,样品可保存8d。GC was applied to the determination of methyl tertiary butyl ether in industrial waste gases. The sample was absorbed by charcoal tube and desorbed by CS2. The analyte was separated on FFAP quartz capillary column （50 m×0. 32 mm, 0. 5 μm）, and detected by FID. Linear relationship between values of peak area and mass concentration of methyl tertiary butyl ether was kept in the range of 1.48--185 mg · L-1 , with detection limit （4S/ N） of 0. 3 mg · L-1. Precision of the method was tested at 3 concentration levels for 6 determination, values of RSD＇s found were in the range of 2.6%--5.7%. The sample can be kept stable for 8 d, at 6 ℃.
