Ion Exchange of Th(IV), U(VI), and Pu(IV) on Macroreticular Resins in TBP-Shell Sol-T Solutions

Abstract
Absorption of thorium, uranium, and plutonium by macroreticular cation and anion exchange resins from solutions of TBP in Shell Sol-T as a function of TBP and HNO3 concentrations in the organic phase has been investigated. The absoiption behavior is compared with that on conventional gel-type resins from TBP medium on the one hand and on macroreticular resins from aqueous nitric acid on the other.
