METHOD OF EXTRACTING NI-63 FROM AN IRRADIATED TARGET AND CLEANING IT OF IMPURITIES Russian patent published in 2020 - IPC G21G4/00 

FIELD: technological processes; nuclear physics.

SUBSTANCE: invention relates to the technology of extracting and purifying radionuclide ⁶³Ni preparation and extracting and purifying nickel from industrial wastes. Purification of target radionuclide from ⁵⁹Fe, ⁶⁰Co, ⁵¹Cr, ⁵⁴Mn, ¹²⁴Sb, ⁴⁶Sc, ¹¹⁷Sn is carried out by deposition of said impurities at pH=5–6 after isotopic dilution with inactive cobalt and oxidation of the latter with potassium or sodium persulphate. Preset pH is maintained by adding to solution of insoluble calcium or barium carbonates.

EFFECT: technical result is possibility of extraction and purification of large quantities of ⁶³Ni (tens of grams) of impurities: ⁵⁹Fe, ⁶⁰Co, ⁵¹Cr, ⁵⁴Mn, ¹²⁴Sb, ⁴⁶Sc, ¹¹⁷Sn, ⁶⁵Zn from targets without adding additional contaminants.
