摘要
通过对吸烟机接口的改装,应用酸化的2,4二-硝基苯肼的乙腈溶液作为吸收液,对主流烟气中的甲醛、乙醛、丙酮、丙醛、丙烯醛、丁醛、丁烯醛、丁酮进行衍生化,形成相应的苯腙,采用紫外检测器在波长为360nm处进行检测,方法的最小检测限在0.54—1.65ng.μl-1之间,样品中被检测物的RSD值在6.22%—12.34%(n=6)之间.
The joint of smoking machine was redesigned, and 2,4-dinitrophenylhydrazine in acidic acetonitrile solution was used to absorb formaldehyde, acetaldehyde, acrolein, acetone, propionaldehyde, crotonaldehyde, methyl ethyl ketone and butyraldehyde in mainstream smoke, and formed 2,4-dinitrophenylhydrazones, which were determined by high performance of liquid chromatography using UV detector at 360nm. The lowest detection levels of method were 0. 54-1. 65ng·μl^-1 , and RSD were 6.22%-12. 34% （n =6）. Some brands of cigarretts were determined and the results were content.
