A Method for Determination of Phthalate Esters in Food by Improved Essential Oil Distillator

概要

論文の詳細を見る
Analysis of phthalate esters by a partly modified essential oil distillator was examined, and approximately satisfactory recovery was obtained with water, non-fatty food and fatty food by taking samples containing about 2g of organic substance (protein and carbohydrate). Over 99% of organochlorine pesticides and PCB, which show an interfering peak in the gas chromatogram, were removed by the combination of zinc powder addition, refluxing and Florisil batch method. In the final procedure of this pretreatment, a known quantity of pyrene was added, and since determination was made by the internal standard method, precision of the determination was improved. Further, the number of reagents and apparatus used were so small that the blank values became lower.
