摘要
目的：检测营养制剂善存片中各种微量元素的含量，并就样品前处理及测定进行方法学探讨。方法：采用３ 种不同方法处理善存片样品，然后用电感耦合等离子体发射光谱仪优化测试条件后，测定铁、镁、锌、锰、铬、钼、钙等１１ 种微量元素的含量。结果：各种微量元素的含量与药盒所标数据基本一致。结论：确定了先用硝酸消化，再用石墨炉灰化为最佳样品处理方法。测定时选４ 点作标准工作曲线，既不会使操作太复杂。
Objective: The levels of the trace elements in the medicine were measured, and some factors concerning the analytic methods were discussed. Methods: The samples were prepared in three kinds of ways and then were detected by ICP. Results: The content of the trace elements is accordant with the known results.Conclusion: To digest the samples by nitric acid and then by high temperature is the best method. The standard curve including four points was applied to ensure the accuracy.
