Coprecipitation of Trace Elements with Iron and Manganese Oxides

3 Coprecipitation of Trace Elements with Iron and Manganese Oxides 

The solubility and reactivity of Fe(III) and Mn(IV) oxides are regulated by pH and Eh. They are soluble under reducing or acidic conditions, thus resulting in the release of trace elements. As discussed before, Mn(IV) oxides are present in a dissolved form at a higher Eh and pH than Ee(III) oxides. Thus, any trace elements released as a result of the dissolution of Mn(IV) oxides can be retained by Ee(III) oxides.
