原子吸收光度法测定渣样中的低含量金属元素

Determination of Low Content Metal Element Used of Atomic Absorption Photometry

利用原子吸收光度法连续测定渣样中的Ｍｇ、Ｍｎ、Ｐｂ、Ｚｎ、Ｃｕ、Ｋ、Ｎａ、Ｌｉ含量，称样、溶样只需一次，就可完成８种元素的连续测定。该方法操作简便、快速，而且测定结果准确可靠，测定各元素的相对标准偏差为０．３％～２５％，回收率达９７％～１０２％。

Through once weighing sample and dissolving sample , the elements of Mg , Mn, Pb, Zn , Cu, K, Na , Li can be determined continuously in slag sample used of atomic absorption photometry. The feature of this method is convenient operation,determining accuracy. The relative error of determined elements is 0.3% ~ 2.5%, the recovery ratio is up to above 97% -102%.
