Elution of uranyl carbonate from a strong base resin with a mixed carbonate eluant in a fluidized system
The system consisted of a multiple-compartment ion-exchange (MCIX) elution column with a continuous flow of solution, except for short periods when the resin increments were withdrawn. The exchange of uranyl carbonate from the mill loaded strong base resin with an eluant composed of 1.0 M Na/sub 2/CO/sub 3/ plus 1.0 M NH/sub 4/HCO/sub 3/ was studied. The effects of solution flow rate, aqueous-to-resin flow ratio, column diameter, compartment height, initial resin concentration, and column length were examined. The experimental data indicate that for the eluant examined a resin residence time of 240 minutes is necessary to attain 90-percent elution efficiency. Also provided is a technique for sizing an elution MCIX column form pilot plant experimental data. 18 figures, 2 tables.
