| Abstract: | Analyzed the experimental process that determination of As in iron ore by microwave digestion ICP-AES method and researched the uncertainty of measurement. Stated the main sources of uncertainty in the process of determination and evaluated and combined the components of uncertainty. The compound uncertainty, expanded uncertainty and confidence interval of a sample were gained. |
