Separation of Zirconium and Uranium.
U S Patent Number 4 381 287 1983 Apr; :
Zirconium- and uranium-containing hydrocarbon-amine solutions are treated for the separation of zr and u by selectively stripping the zr with an aqueous chloride solution (e.g., NaCl or HCl) and scrubbing the resulting aqueous solution with chloride-loaded hydrocarbon-amine solution to selectively remove u, thereby yielding an aqueous zr solution of low u content. The hydrocarbon-amine organic solutions consist essentially of water-insoluble Tertiary amine (alamine 336) and a diluent (e.g., kerosine) for the amine.
