| 摘 要： | 建立固相萃取净化-气相色谱-质谱分析食用油中16种邻苯二甲酸酯的方法。样品用正己烷溶解,过SPE净化柱,采用气相色谱-质谱在选择离子检测(SIM)模式下进行定性、定量分析。结果表明:16种邻苯二甲酸酯在10～10 000μg/L范围内线性关系良好,平均加标回收率为70.0%～110.1%,相对标准偏差为2.68%～11.83%,检出限为10～15μg/L。

| Abstract: | A method for detecting 16 kinds of phthalates simultaneously in edible oils by SPE and gas chromatography-mass spectrometry(GC-MS) was established.Samples were diluted by n-hexane and cleaned up with SPE column.The phthalates were determined qualitatively and quantitatively by GC-MS in selected ion monitoring(SIM) mode.The results showed that the linear range of 16 kinds of phthalates was 10-10 000 μg/L,the recovery rates were in the range of 70.0%-110.1% with relative standard deviations being 2.68%-11.83%,the detection limits were 10-15 μg/L. |
