Determination of Tris Phosphate in Food Packing Materials by Gas Chromatography-mass Spectrometry

介绍了用气相色谱一质谱检测法测定食品包装材料中三（1，3-二氯丙基）磷酸酯含量的方法。试验结果表明：三（1，3-二氯丙基）磷酸酯的线性范围为0．1～50mg／L，检出限为0．04mg／kg，方法的加标回收率为92．5％～95．2％，相对标准偏差为2．50％～3．96％。

An analytical method for determination of Tris （ 1,3-diehloro-2-propyl ） Phosphate （TDCP） food packing materials was established by gas chromatography-mass spectrometry method. The linear ranges TDCP were 0.1 -50 mg/L, and the detection were 0.04mg/kg. The method recoveries were in the range 92.5% -95.2%, and the method precisions were 2.50% -3.96%. in of of
