摘要
对火焰原子吸收光谱法测定饲料级硫酸锰中有害元素——铅含量的测定过程进行分析,按照测量不确定度评定的通用规则建立数学模型,计算了测量过程中的不确定分量,得出合成不确定度和相对扩展不确定度,达到了对其测量不确定度合理评定的目的。
According to JJF 1059-1999 and the corresponding math-model,the determination of lead in feed grade manganous sulphate by FAAS was evaluated. The sources of uncertainty were analyzed in detail. Furthermore, the combined standard-uncertainty and expanded-uncertainty were gave out. The aim of reasonable evaluating the uncertainty of measurement was achieved.
