Abstract
Objective Analysis of the uncertainty in the measurement of lead in human urine by graphite furnace atomic absorption spectrometer was intreduced in this article.The sources of uncertainty and their effects on the total uneertainty were also analyzed.Methods Construct the mathematical model for evaluation of uncertainty in measurement based on a comprehensive understanding of the whole procedure of the determination.Results The measurement result of lead in human urine was given as (334.5±12.0)μg/L.Conclusions The major factor in influence on the determination of lead in human urine was the working curve fitting introduction error.关键词
