Abstract
An electrodialysis cell intended to be used for the electrolytic rejuvenation of ferricyanide bleach bath into ferricyanide comprises a vessel which is made of carbon and which serves as anode, and a cathode, the space defined by both electrodes being separated by a cationic permeable membrane which is a wall made of asbestos cement which has been treated with a strong acid to remove a substantial part of the cement. The elements of the cell preferably have a cylindrical structure and are concentrically arranged with respect to each other.
