| 摘 要： | 以3 mL HNO3和2 mL H2O2的混合消解液对烟草样品进行微波消解,采用电感耦合等离子体质谱测定了烤烟中的Mn、Zn、Cu、Se、N i、Co、Cr、As、Cd、Pb 10种微量元素的含量.结果表明：方法的检出限均低于0.02μg/g,各元素测定的RSD（n=5）均小于3%,样品加标回收率为97.35%-101.30%.方法消耗试剂少,快速准确,适合烟草中多种微量元素的同时测定. |

| Abstract: | 3 mL of HNO3 and 2 mL of H2O2 were chosen for the sample digestion,10 trace elements(Mn、Zn、Cu、Se、Ni、Co、Cr、As、Cd、Pb) in flue-cured tobacco samples were determined by ICP-MS with microwave digestion.All the detection limits of 10 elements were less than 0.02 μg/g and all the RSDs(n=5)of elements were less 3%.The recoveries of spiked samples were in the range of 97.35% and 101.30%.The results show that the method is simple,rapid and accurate,and can be applied to the analysis of trace elements in flue-cured tobacco. |
| Keywords: | ICP-MS flue-cured tobacco microwave digestion trace elements |
