| Abstract: | According to JJF 1059-1999 Evaluation and Expression of Uncertainty in Measurement,the nondeterministic degree of selenium in water with graphite furnace atomic absorption spectrophotometry method in analysized by nondeterministic degree evaluation and indicate theory.The evaluation step and its method of nondeterministic degree explained to get the evaluation results.Results The uncertainty of the result of selenium in water tested by graphite furnace atomic absorption spectrometry is 0.014 mg/L as absolute value and 3.3 % as relative value.Conclusion The method for determining selenium from water by atomic absorption spectrometry is clear and adequate and without repeated procedure.This method has high application value. |
