| Abstract: | A simultaneous determination method was developed for quantification and confirmation of ketone harmful substance in shoe-used adhesives by gas chromatography-mass spectrometry （GC-MS）. It nsed undecane as internal standard. The 3 kinds of ketone hamlful substance were extracted with butyl acetate, and then determined by GC-MS under the selected ion mode （SIM）. The calibration curves showed good linearities in the range of 4-320 mg/L with correlative coefficients （r） larger than 0.99. The average recoveries were 90 %-102 % with relative standard deviations （RSD, n=6） of 2.1%-4.1%. The limits of detection （LOD, S/N≥3） were 0.01 g/kg. |
