Possible Interaction: Manganese and Manganese Cation (2+)

“During the reaction of Se(IV) and δ-MnO2, Mn(II ) was produced and adsorbed strongly on Mn oxide surfaces, which was evidenced by the total reflectance Fourier transform infrared (ATR-FTIR) results.”

“As a result, in the co-presence of Mn2+ and Na+, a small amount of Mn2+ (5 μM) could efficiently neutralize the negative charge of MnOx , thereby decreasing the amount of Na+, which mainly destabilized nanoparticles through electric double-layer compression, required to initiate aggregation.”

“The presence of Mn(II) was also found to enhance the removal of NNH4 in the systems filled with either form of manganese oxides , otherwise the removal of NNH4 was negligible or negative.”

“Under these conditions, the aggregation of Mn oxides reduces the supply of dissolved O2 and/or Mn2+ and inhibits the Mn(II) -> Mn(III) step controlling the enzymatic oxidation of Mn(II).”

“ Manganese XANES revealed small increases in absorption in the spectral region associated with Mn(II ) after reaction, indicating sediment Mn reduction.”

“ABSTRACT A common form of biocatalysis of Mn(II) oxidation results in the formation of biogenic Mn(III, IV) oxides and is a key reaction in the geochemical cycling of Mn.”

“Nutritional supplementation with Mn(II) favored occupancy of the MnSOD active site with manganese and allowed anaerobic accumulation of Mn2-MnSOD in the absence of diamide.”
