不同产地金银花中铜锰微量元素的测定

Determination of Trace Elements Copper and Manganese in Honeysuckle from Different Regions

[目的]测定不同产地金银花中铜锰微量元素的含量。[方法]采用混酸HNO3-HClO4（4＋1）消解样品，火焰原子吸收光谱法测定河南、山东及四川三地金银花中Cu、Mn微量元素的含量。[结果]三产地金银花中都富含锰元素，铜的含量较少，RSD在0.35%~1.80%，回收率在98.0%~104.2%。[结论]对河南、山东及四川三地金银花中铜锰元素含量进行比较，为三地金银花的进一步研究和应用提供了相关数据参考。

Objective]The aim was to determine the contents of trace elements of copper and manganese in Honeysuckle from different habitats. [Method]Using mixed acid HNO3-HClO4 （4＋1） digestion, the contents of trace elements of copper and manganese in Honeysuckle from Henan, Shandong and Sichuan were determined by flame atomic absorption spectrometry. [Result] The results showed that rich in manganese content in Honeysuckle three origin, less copper. The RSD was 0.35%-1.80%, and the recovery rate was 98.0%-104.2%. [Conclusion] The copper and manganese content in Honeysuckle from Henan,Shandong and Sichuan were compared, and it provided reference data for further research and application of three Honeysuckle.
