摘要:目的建立一种适用于食品包装材料中羟基苯醚的气相色谱/质谱检测方法。方法采用索氏提取法,
以二丙醚萃取提取样品中二苯醚类物质,经色谱分离后采用质谱检测,保留时间、分子碎片峰定性,外标法定
量。结果二苯醚类物质回收率为880~109%,相对标准偏差<3.9%0,检测限0.032-0.067mg。结论本方法
便捷、重现性好。适用于各类食品包装材料中二苯醚类物质检测。

ABSTRACT: Objcctive lo eslablish a method for delermination of diphenyl ether in food packing malerials
using gas chromatography/mass spectrometry. Methods The diphenyl ether in food packing malerials was ex-
tracted by soxhlet extraction with dipropyl ether, and then qualitatively anlyzed using mass spectrometry detector
The diphenyl cher were qualitalively determined by retention time and molecular ragment peaks. The extemal
standard method was applied for the quantification. Results The recoveries of typical diphenyl ether were be-
tween 8810%with RS less than 3 and limit of detection was003-0067 mg/Conclusion The me-
thod is convenient and reproducible lor determination of diphenyl ether [rom the food packing materials
