针对原子吸收光谱法测定金矿石中金的测试过程,详细分析了引入的不确定度来源.结果表明,测定结果的不确定度由标准液配制、样品制备、曲线拟合、样品均匀性以及检验重复性等引入的不确定度分量组成,求得测量结果的标准不确定度和扩展不确定度分别为0.03μg/g和0.06μg/g.通过评定得出影响测量准确度的主要因素,需要在以后的工作中严格按照操作规程,不断提高分析测试质量和样品加工质量.

@@@@According to the testing process for determination of gold in gold ore by AAS,we systematically analyz-ed the source of the uncertainty.The uncertainty of the determination results are made up of the uncertainty comp-onents which include standard compounded,sample preparation,curve fitting,sample uniformity,examination duplication and so on.Measurement results are obtained,with the standard uncertainty of 0.03 ug/g and the expanded uncertainty of 0.06 ug/g.Through the evaluation concluded the main factors influencing the measurement accuracy,and we should operate in strict accordance with the procedures in the later work.
