空气或废气中挥发性醛、酮的气相色谱法测定

Determination of Volatile Aldehyde and Ketone in Air and Exhausted Gas by GC FID.

摘要: 本文研究采用了空气或废气中挥发性醛、酮类化合物在常温下经２，４二硝基苯肼（ＤＮＰＨ）的酸性饱和溶液吸收，分别形成各自的腙，用ＣＳ２萃取后，经气相色谱法（ＧＣＦＩＤ）以３％ＳＥ３０／ＣｈｒｏｍｏｓｏｒｂＷＨＰ８０１００目为固定相和载体，分离测定，对空气或废气中的甲醛、乙醛、丙烯醛、丁醛、丙酮、丁酮、甲基异丁基酮等的测定，获得较满意的结果。

Abstract: This paper provides a method to determinate the volatile chemical compounds of aldehydes and ketones in air and exhausted gas.The compounds are absorbed by the acidic saturated solution of 2,4 dinitrophenyl hydrazine(DNPH)and converted to their hydrazones
