| 中文摘要: |
| 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/m3~0.4 mg/m3 (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%。 |
| 英文摘要: |
| 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/m3 and 0.4 mg/m3 (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%. |
