摘要
对火焰原子吸收光谱法测定铁矿石中钠的不确定度进行分析评定,主要对测量过程重复性、绘制工作曲线、标准溶液以及天平称量的不确定度进行分析评定,找出影响不确定度的主要来源,指导在实际工作中采取相应措施以减小不确定度数值。
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.
