Abstract

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
