摘要:建立塑胶玩具中多环芳烃的气相色谱-质谱检测方法。样品用四氢呋喃溶剂超声提取60 min,提取液
以乙腈净化。以DB-5MS 色谱柱为分离柱,柱温程序:70℃保持1 min,以10℃/min 升温至240℃,保持2 min,
然后以8℃/min 升温至280℃,保持5 min。16 种多环芳烃的质量浓度在0.002~0.18 mg/L 范围内线性良好,相
关系数均大于0.991,定量限为0.12~0.20 mg/kg。测量结果的相对标准偏差为4.2%~7.4%(n=6),加标回收率为
84.9%~116.7%。该方法简单、快速、准确、重现性好,能够满足目前对塑胶玩具中多环芳烃的检测要求。
Abstract:A method for determination of 16 polycyclic aromatic hydrocarbonsion(PAHs) in plastic toys by gas
chromatography-mass spectrometry was established. Tetrahydrofuran was used as solvent, the sample was extracted by
ultrasound for 60 min, then purify with acetonitrile, and separated by DB-5MS chromatographic column, temperature
programing: keeping 70℃for 1 min, with 10℃/min up to 240℃, keeping 2 min, then with 8℃/min up to 280℃, keeping
5 min. 16 PAHs had good linear relationships in the range of 0.002-0.18 mg/L, the correlation coefficients were more than
0.991, the quantitative limits were 0.12-0.20 mg/kg, the relative standard deviations of determination results were 4.2%-
7.4%(n=6), the standard recovery rates were 84.9%-116.7%. The method is simple, rapid, accurate and reproducible, which
can meet the present detection requirements of polycyclic aromatic hydrocarbons in plastic toys.
