| 摘 要： | 采用硝酸-双氧水-高氯酸湿法消解样品，用ICP-AES同时测定中成药黄连上清片中的钾、铁、铬、砷、铅、锰、锌、铜等微量元素．建立了电感耦合等离子体原子发射光谱法(ICP-AES)测定中成药黄连上清片中多种微量元素含量的方法．各元素回收率为89．4％～111．5％，变异系数为0．8％～4．5％．应用本方法测定实际样品，结果令人满意．

| Abstract: | ICP-AES method was established for the determination of metal elements in Chinese medicine Huanglian Shangqing tablets. Method: Sample was digested by HNO3-H2O2-HClO4. Multiplex inorganic elements were measured by ICP-AES at the same time. Results: The average recovery of the method for K, Cr, Fe, As, Pb, Mn, Zn, Cu in Huanglian Shangqing tablets were found to be 89.4%~111.5%, with relative standard deviations (RSD) of 0.8%~4.5% (n=5) for the inorganic elements. Conclusion: The method was applied to the analysis of some practical samples and the results obtained were satisfactory. |
