| Abstract: | In this paper,it is analyzed and evaluated the process of determining uncertainties of sodium in iron ore with flame atomic absorption spectrometry.Moreover,the primary sources influencing the uncertainties were found out by analyzing and evaluating the uncertainties for repetitiveness of measuring process,drawing of working curves,standard solutions and measurement with balance,which could guide us to take responding measures to reduce uncertainties in the practical works. |
