| 摘 要： | 以稀盐酸为吸收液，用气相色谱法测定环境空气中痕量三乙胺，结果表明0．1mol／LHCL和0．2mol／LHCL是环境空气中痕量三乙胺的有效吸收液，吸收后样品稳定性良好。在优化的色谱条件下，气相色谱直接进样，FID检测器测定吸收液中的三乙胺线性好、操作简便、精密度高、检出限低，回收率符合要求。

| Abstract: | Through determining trace(CHsCH2)3N in environmental air by absorption of diluted HC1 solution and gas chromatography, the result shows that both 0. 1mol/1 HC1 and 0. 2mol/l HC1 solution are effective absorption solution of trace (CHsCH2)3N in environmental air and the collected samples are stable. Under the optimized chromatography condition, determination of (CH3CH2)3N through direct injection and detection by FID,the result is characterized by broad linearity range,convenience,high precision,low detection limit and satisfied recycle rate. |
