摘 要：
[目的]建立一种可满足植物油中17种邻苯二甲酸酯类化合物的检测方法。[方法]利用气相色谱三重串联四级杆质谱技术,建立了植物油中17种邻苯二甲酸酯类化合物检测方法并进行了样品测试。[结果]该方法对食用植物油中17种邻苯二甲酸酯类化合物的检测,线性范围为10~1 000μg/L,线性相关系数均大于0.999,样品中的检出限最低达到0.2 mg/kg。17种组分3个浓度梯度(1.0、5.0和10.0 mg/kg)的平均回收率均在80.4%~110.9%,相对标准偏差在2.4%~8.3%。[结论]该方法简便、快速、检出限低、结果准确,可应用于核桃油、菜籽油、玉米油等实际样品中17种邻苯二甲酸酯类化合物的测定。

摘 要：
[Objective] The aim was to establish a method for detecting 17 phthalates esters( PAEs) in edible vegetation oil. [Method] A method for the determination of PAEs in edible vegetation oil by gas chromatography coupled with triple quadrupole mass spectrometry( GC-MS-MS) was established and samples were tested. [Result]The linear range of detection changed from 10 to 1 000 μg/L( r > 0. 999).The detection limits of samples of the 17 kinds of PAEs were 0. 2 mg/kg. The average recoveries of three different concentrations( 1. 0,5. 0and 10. 0 mg/kg) were ranged between 80. 40% to 110. 9% and the relative standard deviations were ranged from 2. 4% to 8. 3%. [Conclusion] This method is simple,quick,accurate,which can be applied to the determination of 17 PAEs in walnut oil,rapeseed oil,corn oil and other edible vegetation oil samples.
