| 摘 要： | 本文对过氧化氢比色法测量棕刚玉中二氧化钛含量的不确定度进行了评定,分析了测量过程中不确定度的主要来源,如测量重复性、溶液浓度、溶液体积、试样溶液定容体积、分取溶液体积等,并对各不确定度分量进行了量化计算。结果表明:过氧化氢光度法测定棕刚玉中二氧化钛含量不确定度的最主要来源是测量溶液浓度所引入的不确定度,其次是测量方法重复性的不确定度。

| Abstract: | This article evaluated the test uncertainty in the determination of titanium dioxide in brown fused alumina by the colorimetric method with hydrogen peroxide. The probable sources of the test uncertainty were analyzed, which were： reproducibility of the test results, solution concentration, solution volume, constant- volume of solution when samPling, suction volume of solution, etc. It was found that the test uncertainty of titanium dioxide in brown fused alumina by colorimetric method with hydrogen peroxide mainly came from the solution concentration and the test results reproducibility. |
