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 acid-overoxidation 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.
本文通过电感耦合等离子体质谱法（ICP-MS）同时测定狼毒中稀土元素和微量元素的条件实验，比较了低温灰化法和硝酸-过氧化氢（HNO₃-H₂O₂）法。结果表明，微量元素采用低温灰化处理的样品和稀土元素采用酸消解处理的样品均满足测定方法要求。准确度在1.21%至15.15%之间，精密度在0.38%至8.54%之间。实验数据证明该方法完全满足中药材样品中稀土元素和微量元素测定的要求。
