ABSTRACT:
A method of electroplating iron or an iron alloy with a solution containing an iron-chelating agent to catalytically cycle the undesirable Fe(III) species back to Fe(II) for electroplating. The iron-chelating agents may be siderophores, specifically, for example, desferrioxamine E, desferrioxamine B, alcaligin, bisucaberin, putrebactin, rhodotorulic acid, enterobactin, vibriobactin, azotochelin, myxochelin, fluvibactin, and serratiochelin.
