Abstract
A method of photochemically reducing iron(III) species in an iron or iron alloy plating solution by adding an additive to the electroplating solution; contacting the additive with iron(III) species to form an iron(III)-additive species; and irradiating the electroplating solution, wherein the radiation is of sufficient energy to reduce the iron(III) in the iron(III)-additive species to iron(II). The additive comprises hydroxycarboxylic acids and their lactones.
