Sorption of radionuclides from complexone solutions in liquid CO₂

Keywords: Americium, Cesium, Liquid carbon dioxide, Sorbent, Sorption

Sorption of ²⁴¹Am and ¹³⁷Cs on ion-exchange resins with different functional groups from complexone solutions in liquid CO₂ was investigated. It was shown that more than 99% of radionuclides could be recovered from liquid CO₂ by using strongly acidic resins or H₂C₂O₄·2H₂O. Ion-exchange capacity of KU2-8 (analog of DOWEX-50-8) in liquid CO₂ was estimated.
