Abstract

A method of preparing a metal containing inorganic ion exchanger in an electrochemical cell is disclosed. In one embodiment, the method comprises: (a) adding the inorganic ion exchanger to the electrochemical cell, wherein the electrochemical cell comprises a conductive electrolyte solution having a liquid phase and a solid phase; (b) depositing metal ions electrochemically into the liquid phase; (c) allowing the metal ions to deposit onto the inorganic ion exchanger during an electrochemical reaction to obtain a metal containing inorganic ion exchanger; (d) collecting the solid phase comprising the metal containing inorganic ion exchanger obtained in step (c); (e) removing remaining metal ions from the liquid phase; and (f) obtaining a substantially metal free liquid phase.
