The method for separating ferrate salts from a solution comprising
providing contact between the solution of essentially of aqueous
hydroxide and the ferrate salts and a surface having a magnetic
attraction, magnetically securing the ferrate salts to the surface; and
eliminating contact between the solution and the surface. Contact is
provided by immersing the surface in the solution, passing the liquid
ferrate mixture over the surface, or combinations thereof. The magnetic
attraction may be induced by permanent magnets, electromagnets, and
combinations thereof. The apparatus for ferrate production comprises an
electrochemical cell having an iron-containing anode, cathode, and an
aqueous hydroxide solution in fluid communication with both the anode and
the cathode, and a magnetic separator in fluid communication with the
aqueous hydroxide solution for separating ferrate salts from the aqueous
hydroxide solution.
