| Abstract: | The sources of uncertainty degree of nickel determination by flame atomic absorption spectrophotometry are analyzed as well as the impacts from the uncertainties on the total uncertainty. The confidence interval for the determination results is gotten. The expanded uncertainty of nickel determination from the water samples is 0. 062mg/L. |
