基于气质联用法的鞋用胶粘剂中6种苯系物的测定

Determination of 6 Kinds of Benzene Homologues in Footwear Adhesives Based on GC-MS

建立了气质联用法测定鞋用胶粘剂中6种苯系物的分析方法。以乙酸乙酯为萃取溶剂,提取胶粘剂中的6种苯系物,优化了仪器分析条件。结果表明,本方法6种苯系物的检出限为35~65 mg/kg,加标回收率为91.9%~98.0%,相对标准偏差为3.8%~7.8%。本方法仪器分析时间短,回收率高,重复性好,结果可靠,适用于胶粘剂中6种苯系物的检测。

An analytical method for the determination of six benzene homologues in footwear adhesive by GC-MS was established.The six benzene homologues in the adhesive were extracted with ethyl acetate as the extraction sol⁃vent,and the instrument analysis conditions were optimized.The results show that the detection limit is 35~65 mg/kg,the recoveries range from 91.9%to 98.0%,and the relative standard deviation is at the range of 3.8%~7.8%.The method has short instrument analysis time,high recovery rate,good repeatability,and reliable results.It is suitable for the detection of six benzene homologues in adhesives.
