摘　　要：建立了气相色谱-质谱法测定12种阻燃剂的方法。以正己烷为提取溶液,超声提取纺织品中的阻燃剂,采用气相色谱法（GC-MS）检测,通过选择性离子扫描特征离子定量分析,实验结果表明：12种阻燃剂的线性范围为5.0～50.0μg/m L,检出限和回收率都较好,相对标准偏差〈5%。本方法前处理简便,能准确、灵敏的检测纺织品中多种溴系阻燃剂和磷系阻燃剂,满足国际法令关于纺织品中阻燃剂的检测限量的要求。An analytical method was established for determination of 12 kinds of bromated and phosphorous restricted flame retardants by gas chromatography. The sample was extracted with hexane by ultrasonic bath and the extract after concentration was transferred into a sample vial for GC- MS analysis. The sample was scanned by Scan / SIM scan and quantitated by monitor ions. The linear ranges of the flame retardants were 5. 0 ～ 50. 0 μg / m L,and the LODs / LOQs and recovery were examined respectively. The relative standard deviations were less than 5%. The pretreatment procedure was simple and the method showed satisfied sensitivity and accuracy that met the testing requirements for various flame retardants in fabric products.
