Abstract

Objective:To establish a graphite furnace atomic absorption spectrometry(GFAAS) method to detect traces of cadmium(Cd) in serum.Methods:Using the stabilized-temperature-platform-furnace coupled with a D2-lamp background correction system,the furnace program for the direct determination of Cd is shown in Table 1.Diluted serum samples were measured directly.Results:This method showed a good linearity in the range of 0 μg/L～3 μg/L(r=0.9999).The detection limit was 0.118 μg/L.The relative standard deviation was 3.5% and the recovery rate was 91.6%～109.2%.Conclusion:The method is simple,accurate and sensitive.It was applied in the determination of traces of Cd in serum and received satisfactory results.
