Abstract

A method for recovering a spent aqueous electrolyte resulting from the electrolytic pickling of metal surfaces, said aqueous electrolyte being a solution of a salt of a chelating acid, and having a pH value of about 3 to 7, characterized by the operations of contacting the spent aqueous electrolyte with a sufficient water-soluble hydroxide to raise the pH value of the spent aqueous electrolyte to at least about 10.5, remove any precipitated solids and contact the resulting solution with at least one cation exchange resin such that the pH value of the solution is reduced to at least 7.
