摘　　要：采用顶空-气相色谱法测定固定污染源废气中甲胺、二甲胺、乙胺、二乙胺和三乙胺,通过优化相关测定条件,使5种挥发性脂肪胺在0.005 mg/L~25.0 mg/L范围内线性良好,方法检出限为0.004 mg/m^(3)~0.4 mg/m^(3)(以采集20 L空气样品计)。5种挥发性脂肪胺的加标回收率为91.0%~113%,6次测定结果的RSD≤7.4%。Methylamine,dimethylamine,ethylamine,diethylamine and triethylamine in waste gas from stationary pollution source were determined simultaneously by headspace-gas chromatography.By optimizing the relevant determination conditions,the linearity of five volatile fatty amines was good in the concentration range of 0.005 mg/L~25.0 mg/L,the method detection limits were between 0.004 mg/m^(3) and 0.4 mg/m^(3)(calculated by 20 L sampling volume).The recoveries of the five volatile fatty amines ranged from 91.0%to 113%,and the RSDs of six measurements were less than 7.4%.
