New manganese solution
WebThe transformation of the sulfonamide antimicrobial sulfamethazine (SMZ) by a synthetic analogue of the birnessite-family mineral vernadite (δ-MnO2) was studied. The observed pseudo-first-order reaction constants (kobs) decreased as the pH increased from 4.0 to 5.6, consistent with the decline in δ-MnO2 reduction potential with increasing pH. Molecular … Web23 dec. 1999 · A method and apparatus for precipitating manganese from acidic sulfate solutions, and more specifically from zinc leach solutions, without removing zinc. A zinc- and manganese-containing solution is treated with an SO2—O2 gas mixture at the appropriate pH and temperature, thereby causing manganese to precipitate as a …
