摘　　要：目的建立有效的阻燃剂使用规范和监管制度,利用微波萃取-GC-MS法测定软包装材料中5种有机磷酸酯阻燃剂的含量。方法以软包装材料为研究对象,样品经微波萃取,采用DB-5色谱柱分离,利用GC-MS进行测定。结果在0.2~50.0 mg/kg范围内,线性相关系数均大于0.9994,线性关系良好;检出限在0.05~0.10 mg/kg之间,定量限在0.2~0.5 mg/kg之间;加标回收率在85.6%~104.7%之间,相对标准偏差为1.3%~2.5%。结论文中方法简便、快速,能够满足软包装材料中对5种有机磷酸酯阻燃剂检测的要求。The work aims to establish an effective flame retardant usage specifications and regulatory system, and determine the content of 5 kinds of organic phosphate flame retardants in soft packaging materials by microwave extraction-GC-MS method. Taking the soft packing material as the research object, the samples were extracted by microwave, separated by the DB-5 chromatographic column, and determined by GC-MS. In the range of 0.2~50.0 mg/kg, the linearly dependent coefficients were greater than 0.9994, and the linear relationship was good; the detection limit was 0.05~0.10 mg/kg and the limit of quantitation was 0.2~0.5 mg/kg; the rate of recovery was 85.6%~104.7% of standard addition, and the relative standard deviation ranged from 1.3%~2.5%. The proposed method is simple and rapid, and it can meet the requirements of the detection of 5 kinds of organic phosphate flame retardants in the soft packaging materials.
