石墨炉原子吸收法测定骨肿瘤患者血清中微量钴

Determination of Trace Cobalt in the Serum by Graphite Furnace Atomic Absoption Spectrometry

本文建立了用石墨炉原子吸收光谱法测定血清中微量钴的方法，血清以（１＋１）ＨＮＯ_３沉淀分离除去蛋白ＴｒｉｔｏｎＸ－１００和ＮＨ_４ＶＯ_３为基体改进剂，直接测定、方法简便、快速。回收率９７．６０％－１０２．１１％。ＲＳＤ＜７．２１％。

A method for the determination of micro amount of Co in serum by GFAAS has been established.The effect of protein in serum have been eliminated by adding(1+1) HNO3.The blood serum was determined directly by adding Triton X-100 and NH4VO3 as matrix modifier.The method is handy and fast,The rate of recovery is 97.6%-102.11%. RSD<7.21.
