The redox potential is a quantitative indicator of the mixed redox potential of all substances in a system, which reflects the relative strength of the redox capacity of the whole system. It is of great significance to delineate the uranium enrichment horizon. The redox potential of sandstone-type uranium deposits controls the geochemical behavior of uranium and other variable valence elements, and is of great significance for accurately delineating uranium-enriched horizons. The potential difference method is used to measure the redox capacity of the sample by means of the oxidant solution, and the magnitude of the potential difference can accurately reflect the reducing ability of the reducing components in the sandstone-type uranium ore sample.
To compare the two methods for the determination of the redox potential (
