Scope
This document describes the reagents or materials, instruments and equipment, samples, experimental steps, data processing, precision, quality assurance, and control for determining the uranium content in uranium ores by potentiometric titration.
This document is applicable to the determination of uranium content in uranium ores, as well as the determination and inspection of pure uranium substances such as metallic uranium and uranium oxide.
The range of uranium content determined by the ammonium ferrous vanadate titration method is 0.01% to 15%, and the determination is not interfered by less than or equal to 10 mg of molybdenum, 4.2 mg of vanadium, 3 mg of cerium, and 5 mg of zirconium.
The range of uranium content determined by the ammonium titanium vanadate titration method is 0.01% to 15%, and the determination is not interfered by less than or equal to 25 mg of molybdenum, 0.1 mg of vanadium, 1.5 mg of cerium, and 4 mg of zirconium.
Generally, the impurity content in uranium ores is less than the above-mentioned interference limits, and the determination is not interfered.
