Electrochemical Recovery of MnO2 from Spent Alkaline Batteries
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. …
