Labile Fe(III) phase mediates the electron transfer from Fe(II,III . . . • Labile Fe (III) influence the electron-donating ability of Fe (II) during phase transformation • Electron transfer from Fe (II) to labile Fe (III) rather than CT was enhanced with increasing Fe (III) content • Fe (III) labile surface can maintain the reductive reactivity of Fe (II) during aging
Atomic-Level Structural Differences between Fe(III) Coprecipitates . . . Studies have shown the superiority of in situ Fe (III) (formed by in situ oxidation of a Fe (II) coagulant) over ex situ Fe (III) (using a Fe (III) coagulant directly) in coagulation, but the reasons remain unclear due to the uncertain nature of amorphous structures
An evolving view on biogeochemical cycling of iron - Nature Recent studies have provided insights into novel processes in the biogeochemical iron cycle such as microbial ammonium oxidation and methane oxidation coupled to Fe (iii) reduction
