Abiotic hydroxylamine nitrification involving manganese- and iron-bearing minerals.

ABSTRACT: Hydroxylamine (NH₂OH) undergoes biotic and abiotic transformation processes in soil, producing nitrous oxide gas (N₂O(g)). Little is known about the magnitude of the abiotic chemical processes in the global N cycle, and the role of abiotic nitrification is still neglected in most current nitrogen trace gas studies. The abiotic fate of NH₂OH in soil systems is often focused on transition metals including manganese (Mn) and iron (Fe), and empirical correlations of nitrogen residual species including nitrite (NO₂^-), nitrate (NO₃^-), and N₂O(g). In this study, abiotic NH₂OH nitrification by well-characterized manganese (Mn)- and iron (Fe)-bearing minerals (pyrolusite, amorphous MnO₂(s),
