以ICP-MS/ICP-AES法联合测定大叶鸡骨草中的19个无机元素,方法的准确性用国家一级标准物质GBW10015、GBW10020对比分析证实。检测结果显示,该方法检出限低,分析速度快,准确可靠;这19种元素的含量顺序依次为Ca>P>Al>Mg>Fe>Mn>Sr>Ti>Zn>B>Cu>Ba>Pb>Ni>Cr>Li>Cd>V>Co。
The determination of 19 inorganic elements in Abrus cantoniensis by ICP-MS / ICP-AES was carried out. The accuracy of the method was confirmed by the comparative analysis of national standard GBW10015 and GBW10020. The results show that the method has the advantages of low detection limit, fast analysis speed and accurate and reliable results. The contents of these 19 elements are Ca> P> Al> Mg> Fe> Mn> Sr> Ti> Zn> B> Cu> Ba > Pb> Ni> Cr> Li> Cd> V> Co.
