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…
