SEPARATION OF TRANSPLUTONIUM ELEMENTS BY TBP EXTRACTION CHROMATOGRAPHY

    Graphical Abstract
    • Abstract
  • Conditions for the separation of plutonium from transplutonium elements andtransplutonium elements from lanthanides by TBP extraction chromatography aredescribed. Investigation was made in the separation of americium from plutoniumwith an eluant of 2.0-7.0 mol/l HNO_3 solution in the presence or absence of Naand Al ions. The separation of americium from europium with an eluant ofDTPA-LiNO_3 solution of various pH was also studied. Distribution ratios ofamericium between the column and the 0.025-0.1 mol/l HNO_3 solution containingNa and Al ions were determined. Separation for fission products was also studied.
