Effects of riboflavin and desferrioxamine B on Fe(II) oxidation by O2
Fundamental Research, 2022 Flavins and siderophores secreted by various plants, fungi and bacteria under iron (Fe) deficient conditions play important roles in the biogeochemical cycling of Fe in the environment.

Fe(II) stability in coastal seawater during experiments in Patagonia, Svalbard, and Gran Canaria [PDF]
Biogeosciences, 2020 The speciation of dissolved iron (DFe) in the ocean is widely assumed to consist almost exclusively of Fe(III)-ligand complexes. Yet in most aqueous environments a poorly defined fraction of DFe also exists as Fe(II), the speciation of which is uncertain.

Absence of solid solution between Fe(II) and Mg(II) hydroxides and consequences on formation of fougerite and smectites [PDF]
E3S Web of Conferences, 2019 As there exists extended solid solutions between ferrous and magnesian silicates, experiments were conducted to check if ferrous and magnesian hydroxides can co-precipitate in a solid solution. Results show that no solid solution forms and instead Fe(II)

Study of heteronuclear complexation in Fe(II)-Fe(III)-Mn(II)-CH3COOH-H2O system [PDF]
E3S Web of Conferences, 2023 Heteronuclear complexation in the Fe(II)–Fe(III)-Mn(II)CH3COOH-H2O system at 318 K and ionic strength of 1.0 mol/l was studied by the Clark-Nikolsky oxidation potential method. The formation of complexes of the composition: [FeL(H2O)5]2+; [FeLOH(H2O)4]+;

The role of green rust in the environment: a review O papel do green rust no ambiente
Revista Brasileira de Engenharia Agrícola e Ambiental, 2005 Iron(II)-iron(III) hydroxy-salts known as green rusts (GRs) initially were identified and studied as corrosion products of steel and iron. Recently they were discovered as minerals present in hydromorphic soils and sediments.

Technical note: Effects of iron(II) on fluorescence properties of dissolved organic matter at circumneutral pH [PDF]
Hydrology and Earth System Sciences, 2021 Modern fluorescence spectroscopy methods, including excitation–emission matrix (EEM) spectra parsed using parallel factor analysis (PARAFAC) statistical approaches, are widely used to characterize dissolved organic matter (DOM) pools.
