火焰原子吸收光谱法测定胖大海中的微量元素Fe、Mn

Flame Atomic Absorption Spectrometric Method for the Determination of Trace Elements Zn and Mn Content in Sterculia scaphigera Wall

采用HNO3∶HClO4(4+1)分解样品,火焰原子吸收光谱法测定胖大海中的微量元素Fe、Mn的含量。结果表明胖大海中微量元素Fe、Mn含量丰富,分别为43.8750μg/g、244.625μg/g,RSD<2.700%,回收率在96.90%～105.0%。

Using HNO3：HCLO4（4＋1） to digest the samples,Fe and Mn in Sterculia scaphigera Wall content were determined with flame atomic absorption spectrometric,and the results showed that Fe,Mn traceelements of the rich content were 43.8750 μg/g,244.625 μg/g,RSD3.05%,respectively,and the recovery was in 96.9%~105%.
