| 摘 要： | 建立了气相色谱-质谱联用测定塑料产品中多溴联苯和多溴联苯醚的方法.以甲苯为提取溶剂,超声提取电子电气产品中多溴联苯(PBBs)和多溴联苯醚 (PBDEs),采用气相色谱-质谱法(GC-MS)检测.SCAN和SIM同时扫描,采用质谱特征离子定量分析.结果表明: 9种多溴联苯(PBBs)和10种多溴联苯醚(PBDEs)的线性关系、检出限、回收率和精密度都较好,RSD均<5.0%,PBBs回收率在97%～111%之间;PBDEs回收率在82%～115%之间.本方法前处理简便,灵敏度高,定性、定量分析准确可靠,且分析时间短,适用于塑料产品中PBBs和PBDEs的测定.

| Abstract: | A method has been developed for the detection of polybromobiphenyls(PBBs) and polybromodiphenyl ethers(PBDEs) in plastic products by gas chromatography-mass spectrometry(GC-MS).The samples were extracted with toluene.Then,the extract was transferred into a sample vial for GC-MS analysis,and scanned by full scan and SIM scan and quantitated by monitor ion.The linear range,rate of recovery,LODs and LOQs of PBBs and PBDEs were examined.The recovery rate of PBBs and PBDEs was ranged from 97% to 111% and 82% to ... |
