ABSTRACT
Soluble Fe(II) is an important reductant in anoxic waters, due to fast redox kinetics of the Fe(II)/Fe(III) couple. However, its availability is limited in neutral and alkaline pH range by the solubility of FeS(s), Fe3(PO4)2, FeCO3(s) and other Fe(II) rich minerals. We have studied the adsorption of Fe(II) on a variety of mineral phases and its reactivity towards organic and inorganic compounds, with wet chemical techniques combined with atomic force microscopy (AFM).
