- Abstract
- The main factors,affecting the accuracy of the spectrophotometric determination of antimony in aluminium and aluminium alloys were discuessed,and the uncertainties of measurements caused by these factors in the determination were evaluated.An expanded uncertainty of 0.000 72%,at 95% confidencel level, was obtained in the determination of 0.006 56% of antimony.
- Keywords
- Spectrophotometric determination; Uncertainties of measurement; antimony
