建立了气相色谱-质谱联用法测定塑料产品中的十溴二苯醚的方法,优化了色谱柱、进样方式、进样口温度、程序升温和离子源温度等仪器条件,十溴二苯醚的质量浓度与峰面积在较宽的范围内呈良好线性关系,方法的检出限为0.1mg/kg。加标回收率为93.2-95.7%,标准偏差为4.51-6.37,该法可满足实际塑料样品的分析检测。
A GC-MS method for the determination of decabromodiphenyl ether in plastic products was established. The chromatographic column, injection mode, inlet temperature, programmed temperature and ion source temperature were optimized. Decabromodiphenyl ether The mass concentration and peak area showed a good linear relationship in a wide range, the detection limit of the method was 0.1mg / kg. The spiked recoveries were 93.2-95.7% and the standard deviations were 4.51-6.37. The method can meet the needs of real plastic samples.
