摘　　要：采用活性炭吸附空气和废气中常见的有机物苯、甲苯、乙苯、对-二甲苯、间-二甲苯、邻-二甲苯、丙酮、正丁醇、苯乙烯和环己酮,二硫化碳解析后用毛细管气相色谱法同时测定,各组分线性响应良好,曲线相关系数≥0.999;灵敏度高,检出限在0.01～0.05μg之间;回收率>80%,与相关国标和企业标准相比,操作简单、实用、快速、准确。完全适合环境空气和工业废气中多种有机物的监测。A quick and effective determination method of ten organic compounds （ benzene, toluene, ethyl benzene; xylene, acetone, butanol, styrene and cyclohexanone） in air has been established. The sample was collected with activated carbon and dissolved with 1.0 mL CS2, 1.0μ L of the solution was injected on a DB-FFAP capillary column （30m × 0.32 i.d.×0.25 μm ） and determined by GC-FID. The ten kinds of organic compounds were separated each other completely. The detected limits in sample Were 0.01.-0.05 μ g. Theaverage recoveries were 〉80%. The relative standard deviations was 〈0.36%. This method is simple, rapid and sensitive.
