摘要
建立了测定电子电气产品塑料部件中的7种多氯化萘(PCNs)化合物的GC/MS法。粉碎后的样品经加速溶剂萃取法(ASE)萃取,并经硅胶小柱净化后,GC/MS法测定。7种多氯化萘的线性范围为:0.01～1.0μg/mL(相关系数R2>0.999),加标回收率为64.0%～99.0%,相对标准偏差RSD为2.2%～9.9%。
A new method for the determination of 7 polychlorinated naphthalenes（PCNs） in plastic components of electrical and electronic products by gas chromatography-mass spectrometry was proposed.The PCNs in plastic samples were extracted by accelerated solvent extraction（ASE） and then purified and separated on a silica solid-phase-extraction column..The calibration curve were linear over the concentration range from 0.01 to 1.0 μg/mL（R2 ≥0.999）.The spiked recoveries were from 64.0% to 99.0% with RSDs from 2.2% to 9.9%（n=6）.
