ABSTRACT
Objective:
To establish a method for the uncertainty evaluation of the determination of benzoic acid.Methods:
The content of benzoic acid was determined by acid-base titration. By constructed mathematics model, the source of the measurement uncer-tainty was analyzed, and the uncertainty components were quantized and combined.Results:
The expanded uncertainty of benzoic acid was 0. 36% and the results were expressed as(99. 99 ± 0. 36%,k=2).Conclusion:
The mathematics model is reasonable and relia-ble,and can be used in the uncertainty evaluation of content measurement of benzoic acid.
