AB  - An improved solid phase extraction (SPE)-high performance liquid chromatography 
      method was established to determine 15 carbonyl compounds, namely, formaldehyde 
      (FOR), acetaldehyde (ACETA), acrolein (ACR), acetone (ACETO), propionaldehyde 
      (PRO), crotonaldehyde (CRO), butyraldehyde (BUT), benzaldehyde (BEN), 
      isovaleraldehyde (ISO), n-valeraldehyde (VAL), o-methylbenzaldehyde (o-TOL), 
      m-methylbenzaldehyde (m-TOL), p-methylbenzaldehyde (p-TOL), n-hexanal (HEX), and 
      2,5-dimethylbenzaldehyde (DIM), in soil. The soil was ultrasonically extracted 
      with acetonitrile, and the extracted samples were derivatized with 
      2,4-dinitrophenylhydrazine (2,4-DNPH) to generate stable hydrazone compounds. The 
      derivatized solutions were cleaned using an SPE cartridge (Welchrom((R)) BRP) 
      packed with N-vinylpyrrolidone/divinylbenzene copolymer. Separation was performed 
      on an Ultimate((R)) XB-C18 column (250 mmx4.6 mm, 5 mum), isocratic elution was 
      performed with acetonitrile-water (65ratio35, v/v) as the mobile phase, and detection 
      was performed at a wavelength of 360 nm. The 15 carbonyl compounds in the soil 
      were then quantified using an external standard method. The proposed method 
      improves the sample processing method described in the environmental standard HJ 
      997-2018: Soil and sediment-Determination of carbonyl compounds-High performance 
      liquid chromatography. A series of experiments revealed the following optimal 
      conditions for soil extraction: acetonitrile as the extraction solvent, 
      extraction temperature of 30 ℃, and extraction time of 10 min. The results showed 
      that the purification effect of the BRP cartridge was significantly better than 
      that of the conventional silica-based C18 cartridge. The 15 carbonyl compounds 
      showed good linearities, and all correlation coefficients were above 0.996. The 
      recoveries ranged from 84.6% to 115.9%, the relative standard deviations (RSDs) 
      ranged from 0.2% to 5.1%, and the detection limits were 0.02-0.06 mg/L. The 
      method is simple, sensitive, and suitable for the accurate quantitative analysis 
      of the 15 carbonyl compounds in soil specified in HJ 997-2018. Thus, the improved 
      method provides reliable technical support for studying the residual status and 
      environmental behavior of carbonyl compounds in soil.
