摘要: 建立了测定主流烟气中6种无机元素的电感耦合等离子体质谱(ICP-MS)方法。该方法采用石英滤片捕集卷烟主流烟气中的粒相物,5%硝酸(体积分数)作为吸收液捕集卷烟主流烟气中的气相物,然后用微波消解法处理滤片,与其他方法不同的是,该方法直接将整片滤片全部消解,消解酸体系为HNO3∶HCl∶HF(6∶1∶2),消解完全,提取率高,结果更准确。结果表明,6种目标元素的线性相关系数均在0.999以上,检出限为1.57~2.51 ng/支,加标回收率为91.2%~107.0%。该方法准确度高,简单快速,适用于主流烟气中砷(As)、铅(Pb)、镉(Cd)、铬(Cr)、镍(Ni)、硒(Se)元素的测定。

Abstract: Establish a method to determination six inorganic elements in mainstream cigarette smoke by ICP-MS. The particulate phase was collected by quartz filter pad, and the gas phase was collected by 5% nitric acid (volume fraction) which as absorbent, and then treatment the quartz filter pad by microwave digestion, different from other methods, the whole filter was digested directly in this method, the digestion acid system was as follows: HNO3∶HCl∶HF(6∶1∶2), digested completely, and high extraction, determined byICP-MS with more accurate results. The results showed that correlation coefficients of the calibration curves of the six elements were all above 0.999, and the detection limits were between 1.57~2.51 ng per cigarette, the recoveries were from 91.2% to 107.0%. This method is accurate, quick and simple, and suited to the determination of As, Pb, Cd, Cr, Ni, Se in mainstream cigarette smoke.

Key words: mainstream cigarette smoke, ICP-MS, inorganic elements, quartz filter pad
