Abstract

 In the alkaline batteries of  Zn/MnO2, the electrolytic manganese dioxide (EMD) is used as cathode that constitutes a very important part of household waste which contributes with heavy metals to the solid urban waste. This paper described the recovery of EMD by electro-oxidation on carbon cloth in acidic leached liquors from spent alkaline batteries. The maximum extraction for Mn and Zn were 43.68% (0.744 molL-1) and 56.11% (0.7321 molL-1) respectively. The voltammograms of a vitreous carbon electrode for EMD formation in leached liquors cycled between 0.00 and 1.4V vs ECS exhibit an anodic peak at 1.2V vs ECS, while a cathodic peak appears at 0.97V vs ECS.  The x-ray diffraction reveals the presence of nsutite (γ-MnO2) and manganite (γ-MnOOH) for all deposits, the morphology of the deposits was observed by SEM.
