Manganese Geochemistry: Eh-pH diagram-stability fields in Natural Water

In this article we are going to investigate the Manganese solubility in natural water with the help of various Eh-pH diagrams. We will also investigate the effect of bicarbonate (alkalinity) and sulfate on Manganese solubility. At the end we will compare the solubility of manganese against iron solubility. Background: In natural surface and groundwater, manganese [...]
