Abstract: 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 quantified 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 coefficients (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.
