1. An electrodialysis method for concentrating electrolytes from a colloidal solution comprising the steps of:

  • providing a probe having anionic and cationic chambers thereof, said anionic and cationic chambers being separated by an impermeable longitudinal portion in said probe, said anionic and cationic chambers further having a respective negative and positive electrode disposed therein;

    subtending an associated aperture to said anionic and cationic chambers of said probe with anionic and cationic semipermeable membranes respectively;

    disposing said probe within said colloidal solution; and

    applying an electromotive force to said negative and positive electrodes from a means for providing said electromotive force whereby dilution of said electrolytes in said colloidal solution is effectuated with a concurrent concentration of said electrolytes in a solvent contained within said anionic and cationic chambers by electromigratory passage of said electrolytes through said anionic and cationic membranes.
