Ion Exchange in the Nuclear Industry | SpringerLink
Abstract. Ion exchange is used in nearly every part of the nuclear fuel cycle — from the purification of uranium from its ore to the final recovery of uranium and transmutation products. Ion exchange also plays a valuable role in the management of nuclear wastes generated in the fuel cycle.
Safe Drinking Water is Essential: Adsorption and Ion ...
The ion exchange treatment process uses special resins to remove charged, inorganic contaminants like arsenic, chromium, nitrate, calcium, radium, uranium, and excess fluoride from water. When source water is passed through a series of resin beads, it exchanges its charged contaminants for the harmless charged ions stored on the resin surface.

Recovery of uranium takes place in the ion exchange columns. The uranium bearing leach solution enters the column and as it passes through, the uranium complexes in solution are loaded onto the ion exchange (IX) resin in the column. The now barren leach solution passes from the ion exchange columns to be reinjected into the formation.
