| ABSTRACT Objective:To develop a gas chromatography-mass spectrometry (GC-MS) method for the determination of 24
phthalate esters in food packaging materials. Methods:The samples were extracted with hexane. The identification and quantification
were performed by GC-MS in the selected ion monitoring (SIM) mode. Results:The calibration curves of phthalate esters showed good
linearity in the range of 0.05 mg/L～10 mg/L (0.5 mg/L～10 mg/L for diisodecyl phthalate(DIDP) and diisononyl phthalate(DINP)) with
the correlation coefficients (r2) between 0.9848 and 0.9998. The limits of detection of phthalate esters in food packaging materials were
from 0.002 mg/kg to 0.05 mg/kg (S/N=3). The average recoveries of 24 compositions spiked in packaging materials were 85.2%～108%
and the relative standard deviations (RSDs, n=6) ranged from5.9%to 10.2%. Conclusion:This method is fast, sensitive and accurate for
the qualitative and quantitative determination of 24 phthalate esters in food packaging materials. |
