摘　　要：运用不确定度的理论,对活性炭富集分离—碘量法测定金矿石中金含量的不确定度来源及其对不确定度的影响进行分析,并对引起不确定度分量进行了量化计算,建立了活性炭分离富集—碘量法测定金矿石中金的不确定度的评定和计算方法,得出了标准不确定度、扩展不确定度,并以不确定度的形式给出测试结果。Using the theory of uncertainty, we analyzes the main sources of the uncertainty of gold in ore sample by activated carbon enrichment and separation-iodometry and its effects on uncertainty. The component of caused uncertainty is made quantum chemistry calculation. The method of evaluated and calculated the uncertainty of gold in ore sample is established by activated carbon enrichment and separation-iodometry. As a result, the standard and spread uncertainty are gained, and the measuring result should be demonstrsted with the form of uncertainty.
