啤酒中邻苯二甲酸酯的GC-MS测定
Analysis of phthalates in beer by GC-MS
摘要
Abstract
The phthalates (PAEs) in beer were analyzed by GC/MS method in this study.The results revealed that NaCl addition and ultrasound in extracting PAEs from beer sample using n-hexane enhanced extraction efficiency and eliminated emulsification effectively.A method for residual PAEs determination in beer was developed,which was simple,quick,accurate and reproducible.Under the analytical conditions,12 PAEs had good linearity (in the range of 5 ～500 μg/L for DMP,DEP,DIBP,DBP,BMPP,DPP,DHXP,BBP,DEHP and 10 ～500 μg/L for DMEP,DCHP and DPHP) with the correlation coefficient (R2) varying from 0.995 7 to 0.999 7.The average recoveries of three concentrations (25,50,125 μg/L) reached 88.21％ ～ 110.11％ with the relative standard deviation (RSD,n =6) of 0.40％ ～ 5.49％.This method was successfully applied in the determination of PAEs in 20 commercially available beer samples and reliable results were obtained.The method developed in this study is sensitive,simple,accurate and quick,which meets the demand of PAEs determination in beer.关键词
