摘　　要：本文建立了一种用石墨炉原子吸收光谱法测定肿瘤患者血清中微量钴的方法，血清以（１＋１）硝酸沉淀消除蛋白后，加ＴｒｉｔｏｎＸ－１００和偏钒酸铵基体改进剂直接测定。A method for the determination of micro amount of Co in serum of cancer patients by GFAAS has been established.The effect of protein in serum was eliminated by adding (1+1) HNO 3.The blood serum was determined directly by adding Triton X 100 and NH 4VO 3 as matrix modifier.The method is handy and fast.The rate of recovery is 97 60—102 21% with RSD<7 21.
