Zusammenfassung: | An apparatus charges weakly acidic cationic ion exchange resin particles with uranyl ions by contacting the particles stepwise with aqueous uranyl nitrate solution at higher uranium concentrations from stage to stage. An alkaline medium is added to the uranyl nitrate solution in each stage to increase the successive pH values of the uranyl nitrate solution contacting the particles in dependance upon the uranium concentration effective for maximum charging of the particles with uranyl ions. |
