超高效液相色谱(UPLC)同时测定水性胶黏剂中甲醛、乙醛、丙烯醛
建立了超高效液相色谱(UPLC)法同时测定水性胶黏剂中甲醛、乙醛和丙烯醛的分析方法。水性胶黏剂采用去离子水进行振荡萃取,在酸性条件下,经2,4-二硝基苯肼(DNPH)衍生化后,采用ACOUITY UPLC BEH C18 2.1 mm×100 mm(1.7μm)柱为分离柱,以乙腈-水为流动相,采用优化后的条件二极管阵列检测器进行检测,分析时间为8.0 min。结果表明,甲醛、乙醛、丙烯醛的回收率分别为:100.66%、96.57%、99.56%,相对标准偏差为2.1%~3.4%;该方法分析时间短、流动相消耗量少、结果准确可靠,适合于水性胶黏剂中甲醛、乙醛和丙烯醛的快速测定。...

Bibliography: | A method for separation and determination of formaldehyde,acetaldehyde and acrolein in water-borne adhesives was developed by ultra performance liquid chromatography(UPLC).Deionized water was used to extract water-borne adhesives.In acid conditions,three kinds of aldehyde was derived by 2,4-dinitrophenylhydrazine,and were separated on a ACOUITY UPLC BEH C18 column(1.7 μm,100 mm×2.1 mm)column,using water-acetonitrile as mobile phase.Formaldehyde,Acetaldehyde and Acrolein in water-borne adhesives were separated within 8.0 minutes and then determined by UPLC with a diode array detector.The average recoveries of formaldehyde,acetaldehyde and acrolein were 100.66 %,96.57 %,99.56 %,respectively,and the relative standard deviations were in the range of 2.1 %-3.4 %.This is a faster,simpler and solvent-saving method,and is suitable for rapid analysis of formaldehyde,acetaldehyde and acrolein in water-borne adhesives.
