Abstract/NotesAbstract

The article describes a thermodynamic analysis of the formation process of solid manganese phases in oxygenated aquatic environment. The first step of this process is the formation of the compound MnOOH. In the second step the latter in a disproportionation reaction is transformed into a complicated oxohydroxide [(MnO
