摘要
Abstract
This study established a liquid chromatography analysis method for rapidly determining the con-tents of seven aldehyde-ketone compounds in nonionic surfactants.An ODS-3 C18(250 mm×4.6 mm,5 μm)was used as the liquid chromatography column,and a DAD detector was employed.Acetonitrile was used as the eluent,and the Agilent 1260 liquid chromatograph was used to separate and quantitatively determine seven aldehyde-ketone compounds such as formaldehyde,acetaldehyde,propionaldehyde,acetone,propylaldehyde,butanone,and benzaldehyde in nonionic surfactants.The linear correlation coefficient of this method was 0.999 5-1.000 0,the average recovery rate was 93.0%-105.5%,the RSD was 0.6%-2.8%,and the detection limits of the seven aldehyde-ketone compounds were 0.002-0.004 mg/L,while the quantification limits were 0.008-0.013 mg/L.This method has the advantages of high specificity,simplicity,convenience,high accuracy,and stable repeatability for the detection of seven aldehyde-ketone compounds in nonionic surfactants,and is suitable for the rapid detection of the contents of seven aldehyde-ketone compounds in nonionic surfactants.关键词
