石墨炉原子吸收光谱法测定血清中的微量Mn、Ni、Co和Cr

DETERMINATION OF MICRO AMOUNTS OF Mn, Ni, Co AND Cr IN BLOOD SERUM USING GRAPHITE FURNACE ATOMIC ABSORPTION SPECTROMETRY

本文建立了一种用石墨护原子吸收光谱法测定血清中微量Ｍｎ，Ｎｉ，Ｃｏ和Ｃｒ的方法。血清以０．２％硝酸和ｔｒｉｔｏｎＸ－１００混合溶液稀释１０倍后直接测定。方法简便、快速，回收率为９０～１１０％，相对标准偏差为３．２６～４．３８％。

A method for the determination of micro amounts of Mn, Ni, Co and Cr in blood serum using GFAAS has been established. The blood serum was determined directly after it was diluted 10 times by 0.2% nitric acid and Triton X-100 mixed solution. The method is handy and fast. The rate of recovery is 90-110%. The relative standard deviation is 3.26 4.38%.
