Niuhuang Jiedu tablets were digested with HNO3-H2O2 system by microwave digestion. The fourteen trace elements of As, Ca, Mg, Al, Mn, Sr, Ba, Se, Ni, Cd, Cu, Zn, Mo and Pb in the solution were determined by ICP-AES. The ICP-AES result proved to be reliable by adding standard recovery experiment to the process. By comparison with the result of chemical experiment, thr present method was accurate, quickly-accessible, and convenient. It was used for Niuhuang Jiedu tablets with result satisfactory.
采用微波消解-硝酸-过氧化氢体系对牛黄解毒片进行消解。用ICP-AES法测定溶液中砷、钙、镁、铝、锰、锶、钡、硒、镍、镉、铜、锌、钼和铅14种微量元素。通过加标回收实验验证了ICP-AES法测定结果的可靠性。与化学分析法对比，本法准确、快速、简便，用于牛黄解毒片的测定，结果满意。
