ABSTRACT
Objective To establish an accurate, rapid and practical method for determination of lead in whole blood by graphite furnace atomic absorption spectrometry. Methods It can improve the accuracy and precision of the method by digesting blood sample in nitric acid at constant 135℃, adding matrix to standard series, using matrix modifier and changing ashing temperature of the graphite furnace. Results The linear range, detection limit, mean recovery rate and combination coefficient of variation of the method were 0-50 ?g/L, 1.96 ?g/L, 92.2% and 6.5% respectively. Conclusion This method shows some advantages such as low background, little interference, simple, rapid, sensitive, repeatable and accurate.
