| Abstract: |
| In this study it reported an electrochemical generation of ferrate by dissolution of a new material. It discussed the influence of current density, electrolysis time and anode material on current efficiency. A ferrate solution about 286. 87 mol/dm3 was obtained under the optimum conditions : 16mol/L NaOH,J = lOOmA/cm2 , 35 0C , electrolysis duration ( 2. 5h) . The cyclic voltammograms ( CVs) of iron revealed a new anodic wave between - 1. 4 and 0. 7V versus HgO/Hg corresponding to ferrate( VI) production. The CV is strikingly different in that anodic wave with previous papers . where was emerging the peak which was related to the inter-mediator of electro-oxidation of Fe ( III ) species in concentration basic aqueous solution. It should be FeOj- ( Fe( V) species) . The crystalline structure and morphology of particles of the samples are investigated by X-ray diffraction ( XRD) |
