The formaldehyde content of 40 disposable diapers(adult, children, and sanitary
mats) available in the market was examined. To explore and compare the reliability of
the quantitiative determination of formaldehyde content, High performance liquid
chromatography(HPLC) and UV-VIS spectrophotometer after derivatization of compounds
with acetylacetone and HPLC after derivatization with 2,4-dinitrophenylhydrazine were
perfomed. As a result, the standard curve of formaldehyde by the acetylacetone-based
spectrophotometric method was linear in the range of 0.1∼15 g/mL(R2＝1.000). The
best %RSD value was obtained in this method. The detection and quantitation limits of
the acetylacetone-based spectrophotometric method were 0.009 mg/L and 0.028 mg/L,
respectively. Therefore, the acetylacetone-based spectrophotometric method was used to
determine the formaldehyde content of disposable diapers. Follow results were obtained
3.42 ± 2.14 mg/kg for children diapers, 4.13 ± 2.07 mg/kg for ad
