CPC classification number: C23G1/08
Abstract: A METHOD OF REMOVING COPPER-CONTAINING IRON OXIDE INCRUSTATIONS FROM FERROUS METAL SURFACES THROUGH THE USE OF AN O-AMINO THIOPHENOL IN SOLUTION WITH AN ACID CAPABLE OF DISSOLVING THE INCRUSTATIONS. THE USE OF O-AMINO, THIOPHENOL PREVENTS REDEPOSITION OF COPPER AS A PLATING, IMPROVES THE REMOVEL OF IRON OXIDES IN ADDITION TO COPPER AT LOWER TEMPERATURES, AND IMPROVES THE IRON OXIDE REMOVING PERFORMANCE OF THIOUREA IN ACID SOLUTIONS.
