Abstract
In order to use low-level fission palladium in technology, the paladium must be purified to a high degree with respect to foreign radionuclides with close chemical properties—ruthenium, antimony, and silver.
The results of a simulation of an optimized two-cycle extraction scheme for extracting and refining palladium on the basis of one extractant—an aromatic solution of petroleum sulfides: first cycle with nitrate and second cycle with chloride system—are examined.
The behavior of trace concentrations of silver is investigated and it is shown that total deep removal of silver from palladium of not less than 4.107–40 in the first cycle and 106 in the second cycle with a small number of extraction, washing, and reextraction steps can be attained. 2 figures, 3 tables, 6 references.
