摘要
Na、K、Mg是生物体所必须的常量元素,Zn、Fe、Cu是生物体所必须的微量元素,它们都是生命活动的物质基础之一,这些元素一旦在体内失去平衡将会引起生物体代谢紊乱和机体失调,所以测定生物体内这些元素含量以及评价生命活动质量是有重要意义的。本文研究了原子吸收光谱法(FAAS)测定这些元素的实验条件,测定了豚鼠的心、脾、肺、肾、肝中所含有的K、Na、Mg、Fe、Zn、Cu6种金属元素及其分布状况。相对标准偏差(RSD)小于5.0%,平均回收率在96.4%—105.3%之间,方法快速简便,结果准确。为研究Na、K、Mg、Zn、Fe、Cu在实验豚鼠组织中的含量提供了有用的数据。
Sodium, kalium, magnesium, zinc, iron and copper are basic elements for life, which play a very important role in regulation metabolism and the functional order of organism, and it is significative to determine those metal elements and evaluate the functional life quality. Those six metal elements in the heart, spleen, lung, kidney and liver of guinea pig were determined by flame atomic absorption spectrometry. The result shows that the relative standard deviation（RSD） is smaller than 5.0%, and the addition standard recovery （ASR） is 96. 4%-105. 3% for all the elements. The experimental method is simple, rapid and high accurate,precise,and useful for determination of those six metal elements in organism of guinea pig.
