摘要
采用微波消解法处理样品,研究了微波消解和ICP MS的测定条件,测定了咀嚼片中Cr、Mn、Cd、As、Sn、Ni、Zn、Co、Ag、Pb、Se、Te 12种元素含量,在最佳实验条件下,方法测定下限介于0 .0 1μg/g～0 .10 μg/g之间,RSD均小于5 % ,加标回收在97～10 3%之间。
A method for determination of Cr、Mn、Cd、As、Sn、Ni、Zn、Co、Ag、Pb、Se、Te in rape pollen chewing tablet by Microwave Digestion-ICP-MS was reported.The conditions of Microwave Digestion and ICP-MS determination were studied.Under optimum conditions,the determination limits for 12 elements were in the range of 0.01 μg/g～0.10 μg/g and the RSD were less than 5% with 97～103% recoveries.The method has been applied to the determination of rape pollen chewing tablet.
