Title:
METHOD OF PREVENTING EXTRACTION OF TECHNETIUM AND/OR RHENIUMON EXTRACTION OF URANIUM AND/OR PLUTONIUM PARTICULARLY BY ORGANIC SOLVENT
Document Type and Number:
Japanese Patent JPS623694
Kind Code:
A
Abstract:
Process for preventing the extraction of technetium and/or rhenium, particularly during the extraction of uranium and/or plutonium by an organic solvent. This process permitting the extraction of a chemical element, such as uranium or plutonium present in an aqueous solution containing both said element, technetium and/or rhenium and zirconium and/or hafnium consists of contacting the aqueous solution with an organic solvent able to extract said element, wherein for preventing the extraction of the technetium and/or rhenium with said element, to the aqueous solution is added a zirconium and/or hafnium complexing agent in a quantity adequate for complexing all the zirconium and/or hafnium, said agent being soluble in the aqueous solution.
