| Abstract: |
| In order to investigate the migration of aromatic amines from different paper packaging materials into foods,a solvent extraction/gas chromatography-mass spectrometric（GC-MS） method was developed for the detection of aromatic amines in paper packaging materials and food simulants,using modified polyphenylene oxide（Tenax） as food simulant.The pretreatment method of sample and GC-MS condition were studied.The paper packaging material sample was extracted by ultrasonic extraction for 30 min using 10 mL tert-butyl methyl ether as solvent.The Tenax sample was extracted by ultrasonic extraction for 15 min using 10 mL n-hexane as solvent.The extract was separated with a DB-17 capillary column under selected ion monitoring（SIM） mode.The targets were quantitatively analyzed by the internal standard method using naphthalene-d8,2,4,5-trichloroaniline and anthracene-d10 as three internal standards for the corresponding aromatic amines.The calibration curves of 20 aromatic amines were linear in the range of 0.001 4-0.14 mg/dm2,with correlation coefficients（r） greater than 0.998 and detection limits of 0.000 1-0.000 3 mg/dm2.The relative standard deviations（RSD） ranged from 1.9% to 6.9%,and the recoveries were in the range of 80.6%-107.2% for both paper packaging material sample and Tenax.The method was applied in analysis of the migration of aromatic amines in two types of paper packaging materials.The results indicated that the small molecular weight and low boiling point aromatic amines had a certain degree of migration under the investigated conditions.The method was simple,quick,sensitive and reproducible,and could meet the requirement for the determination of the migration of aromatic amines in paper packaging materials. |
