摘要
本文提出了中草药漏芦中多种微量元素的等离子体原子发射光谱 (ICP AES)同时测定的方法 ,并以GBW 0 85 0 1桃叶标准样进行对照测定。标准样的测定值与参考值吻合较好 ,试样分析结果满意。该方法具有灵敏、准确及多元素同时测定、操作简便、快速等优点 ,适应于中草药及其各种剂型中多元素同时测定。
A method for the simultaneous determination of multiplex trace elements in Chinese herbal medicine Loulu by inductively coupled plasma atomic emisstion spectrometry(ICP AES) has been presented.The operating condictions and the suitable internal standard elements were selected.The detection limits of the method are 0 005-1 24 μg·mL -1 for Fe、Mn、Cu、Ti、Cr、Ba、Sr、Zn、Al with relative standard deviations(RSD) of 1 20%-3 90%(n=7).The recoveries of most elements are in the range of 90 1%-104 2%.The method proposed has been applied to the analysis of real samples and biological standard samples (GBW 08501) peach leaves.The determined values of trace elements in the biological standard sample were in good agreement with the certified values.
