Determination of 17 Phthalic Acid Esters in Fatty Food by Dispersive Solid Phase Extraction-Gas Chromatography-Mass Spectrometry
摘要
Abstract
A method was developed for the determination of 17 phthalic acid esters in fatty food by dispersive solid phase extraction-gas chromatography-mass spectrometry (d-SPE-GC-MS). Tea milk samples were extracted with acetonitrile: methyl tert-butyl ether (9∶ 1, V/V) , and the extract was cleaned up by MAS-PAEC d-SPE column. Flavor seasonings samples were extracted with acetonitrile (saturated with hexane) : methyl tert-butyl ether(19∶1, V/V) , and the extract was cleaned up by CNW d-SPE column. Matrix-match external standard method was used for quantification. The results showed that the average recoveries of 17 phthalic acid esters in milk tea were 82. 2%-125. 4% and relative standard deviations were less than 16. 5%. The limit of detection(LOD) of all the compounds were 100 -200 μg/kg. The average recoveries of 17 phthalic acid esters in flavor seasonings were 70. 9%-115. 5% and relative standard deviations were less than 9. 8%. The limits of detection(LOD) of all the compounds were 400 -800μg/kg. The method is quick, sensitive, easy, cheap, rugged, and can be applied to the detection of 17 phthalic acid esters in fatty food.关键词
