NTIS: PB 80-102536 :20 pages
The Bureau of Mines evaluated the 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(MCIX) elution column with a continuous flow of solution, except for short periods when the resin increments were withdrawn.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 na2co3 plus 1.0 M nh4hco3 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 time of 240 minutes is necessary to attain 90-percent elution efficiency. Also provided is a technique for sizing an elution MCIX column from pilot plant experimental data.
