Abstract:
Process and station for stabilizing an aqueous solution of an iron salt of an organic acid with a ferric component and a ferrous component of less solubility than the ferric component, such as the aqueous solution based on the Fe3+ salt of meso-tartaric acid. To stabilize the content of the dissolved ferric salt, the solution is at least partly subjected to electrolytic oxidation.
