Abstract
A process for synthesizing iron(III) hexacyanoferrate(II) as a blue insoluble product on the surface of a working electrode is disclosed which comprises immersing a pair of electrodes in a solution mixture of an iron(III) ion-containing solution and a hexacyanoferrate(III) ion-containing solution and effecting electrolysis with one of the electrodes as an anode and the other as a cathode, whereby iron(III) hexacyanoferrate(II) is deposited on the surface of the cathode.
