DISPLACEMENT CHROMATOGRAPHIC METHOD FOR SEPARATING URANIUM ISOTOPES

摘要

A salient part of the disclosure describes a method for separating U235 isotope from U238 isotope comprising introducing a solution containing a reducing cation such as Ti<+>3 into a cation-exchange resin column, thereafter introducing a uranyl solution containing both U235 and U238 isotopes, followed by introduction of a solution containing an oxidizing agent such as Fe<+>3 and thereafter separately recovering uranyl solutions containing uranium which is enriched in U235 isotope and uranium which is correspondingly depleted in U235 isotope.
