表面增强拉曼光谱法测定食品接触用塑料材料及制品中4,4'-二氯二苯砜的迁移量
Determination of 4,4'-Dichlorophenyl Sulfone Migration from Plas-tic Food Contact Material Products by Surface Enhanced Raman Spectroscopy
摘要
Abstract
Surface enhanced Raman spectroscopy(SERS)was used to detect the migration of 4,4'-di-chlorophenyl sulfone from plastic food contact materials.Au nanoparticles were prepared for SERS substrate and characterized,then the Raman characteristic peaks of 4,4'-dichlorophenyl sulfone were assigned by theoretical calculation.The migration behavior of 4,4'-dichlorophenyl sulfone in plastic food contact material products was carried out according to the GB 31604.1-2015 and GB 5009.156-2016.The obtained solution was passed through a 0.22 μm filter membrane,and mixed with AuNPs to perform SERS test,and the results were validated by high performance liquid chroma-tography(HPLC).The intensity of the characteristic peak(748 cm-1)of 4,4'-dichlorophenyl sulfone showed a good linear relationship with the mass concentration of 4,4'-dichlorophenyl sulfone in the range of 0.05-10 mg/L,and the correlation coefficient was 0.992 8,the recoveries of SERS method were 85.2％-93.4％with the relative deviations of 4.2％-6.6％,meanwhile,these results were in good agreement with the HPLC.The proposed method was applied to the determination of 4,4'-di-chlorophenyl sulfone in 5 brands of polyphenylene sulfone(PPSU)milk bottles.This method is rapid,accurate and user friendly,and provides a technical reference for the determination of 4,4'-dichlo-rophenyl sulfone in food contact materials and products.关键词
