Uncertainty Evaluation on Measurement Results of Micro-amount Uranium in Uranium Ores by 5-Br-PADAP Spectrophotometry with P256 Strong Basic Anion-exchange Resin Separation and Enrichment

The uncertainty on measurement results of micro-mount uranium in uranium ores by 5-BrPADAP spectrophotometry with P256 strong basic anionexchange resin separation and enrichment was evaluated. The main sources of the uncertainty were analyzed. The uncertainty expression and mathematical models for calculating each parameter were proposed. The sub-ncertainties and the expanded uncertainty were also calculated.
