| Abstract: | After microwave digestion of tobacco flavourings and casings with HNO3 and H202 .The lead, cadmium, chromium, nickel, arsenic and mercury elements were tested by ICP-MS. The results showed that the detection limits are in the rang e of 0.091- 0.305 ug/L. The recovery of six elements were from 88.6 % to 103.5 % and RSD were from 1.3 % to 8.5 %. The results proved that this method is simple, accurate and reliable for analysis of trace ead, cadmium, chromium, nickel, arsenic and mercury in tobacco flavourings and casings. |
