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, acrole-in, 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 at 40 °C for 20 min. The optimized chromatograpic conditions were as follows: DIONEX Acclaim Explosives E2 reversed-phase column as separation column, water and acetonitrile as mobile phase by double gradient elution. The flow rate was set at 1. 2 mL/min, and the column temperature was set at 35 ℃. Under the optimal conditions, the linear ranges of 8 carbonyl compounds were all in 0. 001 1 -55. 32 mg/L, with correlation coefficients higher than 0. 999. The limits of detection for 8 carbonyl compounds were 0. 066 3 - 1. 691 1 mg/kg, and the limits of quantitation were 0. 221 -5. 637 mg/kg. The relative standard deviations were between 4. 3% and 9. 3% , and the recoveries were 62% -100% . The established method was sensitive , simple and accurate, and was practical for the determination of 8 carbonyl compounds in water-based adhesive.关键词
