Recovery of Uranium from NaF Sorbent using Ion Exchange Resins

NaF disks are used for the adsorption of UF6 in low concentration. In this paper a wet chemical method is presented for recovery of uranium from NaF disks. In this method the adsorbed uranium on the disks is dissolved in sodium carbonate solution and converted to UO2(CO3)34- and this complex is adsorbed on the ionic exchange resin amberlit-110. By using sodium nitrate solution, UO2(CO3)34- is desorbed from resin. The uranium on the resulting solution can be used in production process of UF6. The proposed method introduced in this paper shown to have high efficiency and convenient operational procedure.
