气相色谱-质谱法同时测定塑料食品接触材料中25种芳香族伯胺的迁移量
Determination of migration of 25 primary aromatic amines from food contact plastic materials by gas chromatography-mass spectrometry
摘要
Abstract
A solid phase extraction ( SPE) combination with gas chromatography-mass spectrometry (GC-MS) was developed for the determination of the migration of 25 primary aromatic amines (PAAs) from food contact plastic materials and articles. The samples were extracted by deionized water and 30 g/L acetic acid, and the pH value of the solution was adjusted to 8 - 10 with ammonia. The extracts were cleaned up and concentrated on an SPE column, then eluted by equal volume of methyl-tert-butyl ether and ethanol. The analysis of the target compounds was performed by GC-MS. The results indicated that the limits of detection were in the range of 0. 4 - 2. 0 μg/kg for different PAAs. The recoveries and relative standard deviations (n = 7) of 10 μg/kg PAAs ranged from 51.6% - 118.4% and 0. 5% - 9. 8%, respectively, except the 2,4-diaminoanisole in the acid simulant. The effects of different experimental conditions such as the pH value and volume ratio of methyl-terf-butyl ether and ethanol were studied. The results showed that the method is accurate and stable, and could meet the requirement of the European Commission Regulation (EU) No 10/2011 for the determination of primary aromatic amines. It can be applied in the analysis of the primary aromatic amines in real food contact plastic material and article samples.关键词
