A potentiometric method has been developed for the determination of uranium in phosphate-perchlorate medium. A significant feature of this method is its applicability for the determination of uranium in uranium-bearing CaF2 slags and fused salt cakes generated at the natural uranium conversion and fabrication plants, respectively. These uraniumbearing slags and cakes contain large amounts of calcium and barium, respectively, where the conventional Davies-Gray and the related methods cannot be applied. A distinct advantage of the present method over coulometric determination of uranium in perchloric acid medium is that it can easily be adopted for routine analysis.
