气相色谱法测定MDI废水中微量苯胺及硝基苯

Determination of Aniline and Nitrobenzene in Waste Water by Gas Chromatography

用标准萃取液萃取样品中苯胺及硝基苯 ,经气相色谱毛细管柱GC/FID测定样品中的苯胺及硝基苯 ,以保留时间定性 ,峰高定量。

Standard extractant is used to extract aniline and nitrobenzene in the sample. Aniline and nitrobenzene in the sample is determinated by capillary column GC/FID. The sample is qualitalively determinated by retention time and quantitatively determinated by peak-height internal standard methods.
