Interaction of ammonium with birnessite: Evidence of a chemical and structural transformation in alkaline aqueous medium
Hella Boumaiza, Romain Coustel, Christelle Despas +2
The ammonium cation interaction with Na-birnessite in aqueous alkaline medium was studied. Solution and solid analysis give evidence that birnessite is not only acting as a cationi…
Conditions for the formation of pure birnessite during the oxidation of Mn(II) cations in aqueous alkaline medium
Hella Boumaiza, Romain Coustel, Ghouti Medjahdi +2
Birnessite was synthetized through redox reaction by mixing MnO4-, Mn2+ and OH- solutions. The Mn(VII): Mn(II) ratio of 0.33 was chosen and three methods were used consisting in a…
Reflexion Mössbauer analysis of the in situ oxidation products hydroxycarbonate green rust
Sebastien Naille, Mustapha Abdelmoula, Didier Louber +2
The purpose of this study is to determine the nature of the oxidation products of FeII-III hydroxycarbonate FeII4FeIII2(OH)12CO3~3H2O (green rust GR(CO32-)) by using the miniaturis…
