摘　　要：采用气质联用法测定鞋类材料中2-苯基-2-丙醇的含量。该方法以叔丁基甲醚为溶剂,在室温下超声提取鞋类材料中2-苯基-2-丙醇,然后进行气质联用仪分析,采用外标法定量。实验表明,在0.05~10 mg/L范围内,定量限为1.0 mg/kg,平均加标回收率为90%~102%,相对标准偏差RSD<4.0%(n=6)。该方法准确,适用于鞋类材料中2-苯基-2-丙醇的测定。The content of 2-phenyl-2-propanol in footwear materials was determined by gas chromatography-mass spectrometry(GC-MS).Using methyl t-butyl ether as the solvent,ultrasonic treatment was conducted at room temperature to extract 2-phenyl-2-propanol from footwear materials.The GC-MS analysis was then carried out,and the quantitative tests were conducted by external standard method.Results show that,when the range of determination was 0.05~10 mg/L,the quantitation limit of 2-phenyl-2-propanol was 1.0 mg/kg,and the spiked average recoveries ranged from 90%to 102%,while the relative standard deviation(RSD)is less than 4.0%(n=6).The present method is accurate and suitable for the determination of 2-phenyl-2-propanol in footwear materials.
