摘　　要：采用气质联用法测定鞋用胶粘剂中甲苯的含量。该方法以乙酸乙酯为溶剂,直接进行气质联用仪分析,外标法定量。实验表明,在0.2~50 mg/L范围内,方法检出限为0.05 g/kg,平均加标回收率为94%~103%,相对标准偏差RSD=1.94%(n=6)。该方法适用于鞋用胶粘剂中甲苯的测定。Determination of Toluenein Adhesivesof footwear by gas chromatography-tandem mass spectrometry(GC-MS).The method is using ethyl acetate as the extraction solvent,and detected by GC-MS and quantifided by external standard method.Results show that in the range of 0.2-50 mg/L,the method detection limit of Toluene was 0.05 mg/kg,and the spiked average recoveries ranged from 94%to 103%,and the relative standard deviationis 1.94%.The method is suitable for the determination of Toluenein Adhesivesof footwear.
