单滴微萃取—气相色谱—质谱联用法检测食品中5种邻苯二甲酸酯类塑化剂
Determination of 5 kinds of phthalate acid esters in food by single drop microextraction combined with gas chromatography—mass spectrometry
摘要
Abstract
To develop a rapid and simple method for the determination of five phthalate acid esters (PAEs) in soy sauce,vinegar,and juice by gas chromatography-mass spectrometry (GCMS) after single drop microextration.The five PAEs was analyzed by GC-MS.Good linearity was obtained for five PAEs at the concentration of 1 ～ 10 mg/mL,r≥0.995.At three different spiked concentration levels,the average recoveries of 5 PAEs in three different samples were between 75.4％ and 113.0％.The intra-day and interday precisions (relative standard deviation,RSD) were 2.4 ％ ～ 7.3 ％ and 1.9％～8.5％,respectively.Among 5 PAEs,the detection rate of DBP was 100％ utmost.The DBP of all the samples was more than the limited standard of 0.3 mg/kg,according to the national standards of GB 9685-2008.5 PAEs in samples packed in plastic bags,plastic bottles and packaging cartons were more than those in samples packed in glass bottles.The method,which is simple,rapid,and high sensitive,is suitable for the determination of 5 PAEs in soy sauce,vinegar,and juice.关键词
