ABSTRACT:
A method for preparing nickel hypophosphite by contacting a nickel anode with a solution of hypophosphite anions and applying a current through the anode to a counter-electrode in contact with the solution to anodically dissolve the nickel of the anode into the hypophosphite solution, thereby forming a nickel hypophosphite solution. A one-compartment electrolysis cell and a three-or-more-compartment electrodialysis cell embodying the method of the invention are described.
