Mn(II) Oxidation in the Presence of Lepidocrocite: The Influence of Other Ions
Creators
Abstract
Mn(II) oxidation is enhanced in the presence of lepidocrocite (γ-FeOOH). The oxidation of Mn(II) on γ-FeOOH can be understood in terms of the coupling of surface coordination processes and redox reactions on the surface. Ca^(2+), Mg^(2+), Cl^- , SO_4^(2-), phosphate, silicate, salicylate, and phthalate affect Mn(II) oxidation in the presence of γ-FeOOH. These effects can be explained in terms of the influence these ions have on the binding of Mn(II) species to the surface. Extrapolation of the laboratory results to the conditions prevailing in natural waters predicts that the factors which most influence Mn(II) oxidation rates are pH, temperature, the amount of surface, ionic strength, and Mg^(2+) and Cl^- concentrations.
