GC-FID法测定食品级瓶盖垫圈中五种邻苯二甲酸酯类增塑剂的含量
Determination of Five Phthalic Acid Esters Plasticizers in Food-Grade Lid Gasket by GC-FID
摘要
Abstract
Gas chromatography-flame ionization detection ( GC-FID) analysis method is used to determine contents of five phthalic acid esters (PAEs) plasticizers, including di-2-ethylhexyl phthalate (DE-HP) ,di-isononyl phthalate (DINP) ,di-isodecyl phthalate (DIDP) ,butylbenzyl phthalate (BBP) and din-butyl phthalate ( DBP) in four kinds of food packaging lid gaskets. The linear relation of this method is much better; and the correlated coefficients of the compounds of five kinds are 0.998 1 ~0. 999 8; and their detection limits are in the range of 0.9 ~2. 9 jxg/mL. The best extracting conditions for determining 5 kinds of phthalic acid esters are selected via experiments; methylbenzene is adopted as the extracting solvent and the extraction time is 5 hours. The recovery rate of the five compounds is 86. 9% ~ 103. 1% , and the relative standard deviation ( RSD) is 3.75%. The results indicate in the four kinds of food packaging lid gasket, the content of DEHP in alcoholic drinks packaging lid gasket and can packaging lid gasket is 23. 3% and 35. 5% respectively, the five kinds of plasticizer are not detected in the rest of other two lid gaskets.关键词
