[Determination of trace Pb in whole blood by Zeeman-GFAAS].
The determination method for trace Pb in whole blood was studied, which was diluted by 0.5% HNO3. In the measurement, Zeeman-GFAAS was used and the relative condition was discussed. This method shows that the detection limit was 10.0 pg, the relative standard deviation of standards (RSD) was 0.36%-1.8%, the relative standard deviation of samples (RSD) was 1.4%-2.3%, and the recovery rate was 96.0%-101.7%. The concurrent interference was low. This method is simple and rapid. It is an ideal method to determine trace Pb in whole blood.
