采用流动注射-等离子体原子发射光谱(FI—ICP—AES)反相标准加入法(也称内插法)对中药漏芦中多种微量元素进行同时测定。对FI和ICP—AES的工作条件进行了试验,提出了优化条件下的测定方法。该法用于中药漏芦中的多种微量元素Fe、Cu、Mn、Cr和Ni的同时测定,分析结果满意,方法具有操作简单,消除基体效应,消耗试样少,精密度和准确度好以及分析效率较高等优点,为中草药中多种微量元素同时测定提供了一个快捷、实用的新方法。 Simultaneous determination of various trace elements in Leuciscus indicus by flow-injection-plasma atomic emission spectrometry (FI-ICP-AES) reversed-phase standard addition method (also called interpolation method) The working conditions of FI and ICP-AES were tested, and the determination methods under the optimized conditions were put forward. The method was applied to the simultaneous determination of trace elements such as Fe, Cu, Mn, Cr and Ni in Leucaena leucocephala with satisfactory results. The method has the advantages of simple operation, elimination of matrix effect, less sample consumption, good precision and accuracy As well as the advantages of high analytical efficiency, etc., for Chinese herbal medicine in the simultaneous determination of trace elements provides a fast, practical new method.
