| Abstract: | A direct derivatization and high-performance liquid chromatographic method was developed for the trace analysis of 8 carbonyl compounds,e.g.formaldehyde,acetaldehyde,acetone,acrolein,propaldehyde,crotonaldehyde and 2-butanone and butaldehyde in water-based adhesive.The method adopted 2,4-dinitrophenylhydrazine(DNPH) to directly react with the adhesive sample solution,and the influence factors were investigated and optimized.The best derivatization condition was using the adhesive to react directly with DNPH... |
