제목 Full Electrochemical divided cell optimization through the redox mediators of free Co(III)/(II) and complex Co(II)(CN)54-/Co(I)(CN)53- : An electrolysis study
초록 A constant current mode of divided electrochemical cell is the only one economically applied to industrial applications. But, one half cell of the full electrochemical cell has been utilized till date,  especially anodic part, as a direct or mediated electrochemical oxidation DEO/MEO using free metal ions. Here, the investigation started to utilize the full electrochemical cell in the form of MEO and MER process. In MER process, utilization of metal complexes like Co(II)(CN)54- are used to stabilize the active low valent state like Co(I)(CN)53-. Being a totally different form of mediators, the operation of the full electrochemical cell is very impractical. Herein, first focus to operate the full electrochemical cell using the different kinds of electrolytes (H2SO4, KOH), combination of electrodes (Pt and carbon) and current densities. The oxidation/reduction process confirmed using measure oxidation/reduction potential changes via ORP electrode. The oxidation/reduction efficiencies calculated using titration with FeSO4 and KMnO4. The surface analysis of membrane and electrode derives to support the sustainable operation of the full electrochemical cell.
