To obtain metal hydroxides in an easily separable pulverulent form, from this metal in solution, the formation of the hydroxide precipitate against an exchange membrane of the solution is caused by passing an electric current through the solution. solid ions, this membrane separating the anode compartment from the cathode compartment. If the solution is an acidic solution, the membrane is an anionic membrane. If the solution is a basic solution, the membrane is a cationic membrane. |
