本文建立了纺织品中1-溴丙烷的气相色谱-质谱(GC-MS)检测方法。本方法中样品经丙酮超声提取后,采用气相色谱-质谱联用全扫描和选择离子扫描方式对提取液进行定性定量分析,外标法定量。结果表明:在0.5~50.0 mg/L范围内,方法的线性关系良好,相关系数达0.999以上;方法检测低限为0.5 mg/kg,定量限为1.0 mg/kg;在1.0、2.0和10.0 mg/kg 3个加标水平下,回收率为82.0%~95.0%,相对标准偏差3.1%~6.2%。

In this paper a gas chromatography-mass spectrometric (GC-MS) method was established for the determination of 1-Bromopropane (1-BP) in textiles. 1-Bp in textiles was extracted by ultrasound with Acetone, the ultimate solution was analyzed by GC-MS under full-scan and selected-ion monitoring mode and quantiifed by external standard method. The results showed that, in the range of 0.5 mg/L~50.0 mg/L, the calibration curve was linear well with good correlation coefifcients (R>0.999);the detection limit was 0.5 mg/kg and the limit of quantitation was 1.0mg/kg;the average recovery was 82.0%~95.0%, and the relative standard deviations (RSD) were 3.1%~6.2%at three spiked concentration levels of 1.0, 2.0, 10mg/kg.
