Abstract

A method for metal ion reduction may comprise introducing a sugar acid solution to a system that may include an electrodialysis unit. The sugar acid solution may include a sugar acid, one or more initial cations, and a solvent. The method may also include subjecting the sugar acid solution to electrodialysis under conditions suitable for removal of the initial cation and formation of a sugar free acid. The method may also include recovering the sugar free acid wherein the sugar free acid has a purity of from about 60% to about 90%.
