Copper and nickel ions in waste solutions can be recovered as metal-formamide complexes with over 90% recovery efficiency. It is possible to use these recovered metal-formamide complexes as electrolyte again for metal plating. The nickel deposit obtained from the regenerated bath has a hardness value of about 500Hv, a strong [200] grain orientation, and a grain size of 88-129Å.
