AB  - A novel method was developed for trace analysis of aliphatic aldehydes and 
      ketones in water-based adhesive based on 2,4-dinitrophenylhydrazine (DNPH) direct 
      derivatization-1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM] PF6) 
      preconcentration coupled with high performance liquid chromatography (HPLC). The 
      dispersive water-based adhesive emulsion directly reacted with 80 mg/L DNPH 
      solution containing 0.44 mol/L phosphoric acid at 40 degrees C for 18 min. After 
      centrifuging, 0.5 mL [BMIM] PF6 was added to extract the derivatives at 30 
      degrees C. The ionic liquid (IL) phase was filtered and then analyzed by HPLC. 
      The separation was achieved by using a Dionex Acclaim Explosive E2 column (250 mm 
      x 4.6 mm, 5 microm) under the gradient elution with acetonitrile and water as 
      mobile phases at the flow rate of 1.2 mL/min. The column temperature was 35 
      degrees C, and the detection wavelength was 365 nm. The results showed that the 
      limits of detection (LODs) were 0.022 -0.221 mg/kg, and the limits of 
      quantification (LOQs) were 0.073 - 0.738 mg/kg. The relative standard deviations 
      (RSDs) were in the range of 3.5% - 7.3%, and the recoveries were 84.0% - 102.5% 
      for 8 aliphatic aldehydes and ketones. Compared with solvent extraction, the 
      established method has the advantages of lower LOD and LOQ, and is more stable 
      and precise. This method is practical for the determination of aliphatic 
      aldehydes and ketones in water-based adhesives.
