HPLC-DAD法检测卷烟滤嘴中挥发性羰基化合物及其截留效率研究

将高效液相色谱-二极管阵列检测法（HPLC-DAD）用于检测卷烟滤嘴中挥发性羰基化合物（甲醛、乙醛、丙酮、丙烯醛、丙醛、巴豆醛、2-丁酮和丁醛）,采用体积比为1∶1的乙腈与水混合溶剂振荡萃取卷烟滤嘴,萃取溶液与2,4-二硝基苯肼衍生化反应后进行HPLC-DAD分析,结果表明：滤嘴中8种羰基物的加标回收率在80.8%~115.7%之间;甲醛、乙醛、巴豆醛的日内及日间精密度较好,RSD均〈10%.考察不同类型滤嘴对卷烟主流烟气中羰基化合物的截留效率,结果表明：滤嘴对8种羰基物总量的截留效率较低,对甲醛、巴豆醛截留效率较高（〉10%）,对其他几种羰基物的截留效率低（〈7.0%）;不同类型滤嘴对甲醛截...

A high performance liquid chromatography-diode array detector（HPLC-DAD） method was developed to determine volatile carbonyl compounds in cigarette filter including formaldehyde, acetaldehyde, propionalde- hyde,acetone,acroein, crotonaldehyde,2-butanone and butyraldehyde. The cigarette filters were extracted by shaking with the mixed solution of acetonitrile and water（ the volume ratio of 1： 1 ）, then reacted with 2,4- dinitrophenylhydrazine,and analyzed by HPLC-DAD. The recoveries of 8 carbonyl compounds in cigarette filters were in the range of 80. 8% and 115.7%. The precisions of intra-day and inter-day for formaldehyde, acetalde- hyde and crotonaldehyde were good （ RSD
