摘要
Abstract
Uncertainty evaluation on the criteria of "ferrous sulfate deoxidization / ammonium vanadate oxidation titrimetry to measure uranium" (EJ267. 2-84) issued by Ministry of Nuclear Industry was analyzed. The uncertainty brought by the method itself was obtained through the identification of uncertainty sources, quantification of uncertainty components and determination of uranium content by titration with calibrated ammonium vanadate solution. With the analytical study to uncertainty sources of entire process and components, and the application of statistical treatment based on scientific data, the combined standard uncertainty and expanded uncertainty about different levels of uranium content was reported.关键词
