[Study of determination method for trace cobalt in serum of cancer patients].
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) 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 97.60-102.21% with RSD < 7.21.
