摘要
研究了电感耦合等离子体质谱法（ICP-MS）测定中草药狼毒中稀土和微量元素的方法，样品处理通过低温灰化方法与硝酸-过氧化氢消解方法比较，实验确认微量元素采用低温灰化法制备样品，稀土元素采用酸消化法制备样品，可以满足该方法检测要求，具有测试方法准确、快速等优点。方法的准确度在1．21％～15．15％，精密度在0．38％～8．54％之间。该方法完全可以满足中草药样品中稀土和微量元素检测要求。
In this article, through the condition experiment of simultaneous determination of rare earth and trace elements in wolfsbane by inductively coupled plasma mass spectrometry.（ICP-MS）, the methods of low temperature ashing and nitric acidoveroxidation hydrogen（HNO3-H2O2） were compared. It was proved that the sample disposed with low temperature ashing for microelements and the sample disposed with acid digestion for rare earth satisfied the request for the method of determination. The accuracy is between 1.21% and 15.15%, and the precision is between 0. 38% and 8. 54%. The data of the experiment proved that the method completely satisfied the request for the determination of rare earth and microelements in the sample of Chinese herbal medicine.
