原子吸收光谱法测定野胡萝卜中的微量元素

Determination of Trace Elements in Wild Carrot by FAAS

采用湿法消化溶解样品，用原子吸收光谱法测定了野胡萝卜叶及根中的Zn、Mn、Fe、Cu等元素的含量。结果表明，该法的平均相关系数≥0．9995；测定样品的相对标准偏差为0．31％．1．60％；样品的回收率在96．30％～105．88％之间，表明该法准确、可靠，测定结果为更好地开发野胡萝卜资源提供了参考依据。

The leaf and root of Wild carrot of were dissolved by HNO3- HClO4. The trace Zn, Mn, Fe and Cu in wild carrot were determined by flame atomic absorption spectrometry （FAAS）. The result shows that the correlative coefficient of the method is ≥ 0. 999 5, the relative standard deviation of examinated sample was range from 0. 31% to 1.60%, the recovery of specimen was range from 96. 30% to 105.88%. It will offer some useful data for developing the wild carrot resource.
