A Study of Fe (II) and Fe(III) Complexes of Fluorescein-Part III.

open access: yes, 1975
Department of Chemistry, Marathwada University, Aurangabad Manuscript received 21 May 1973; accepted 4 February 1975 Complexes of fluorescein with Fe(II) and Fe(III) show anomalous magnetic properties suggest­ing intermolecular interactions. The Miissbauer spectrum of the Fe(III) complex gives proof , to the Fe-Fe interaction.

Unequivocal determination of metal atom oxidation state in naked heme proteins: Fe(III)myoglobin, Fe(III)cytochrome c, Fe(III)cytochrome b5, and Fe(III)cytochrome b5 L47R

open access: yesJournal of the American Society for Mass Spectrometry, 2000
Unambiguous determination of metal atom oxidation state in an intact metalloprotein is achieved by matching experimental (electrospray ionization 9.4 tesla Fourier transform ion cyclotron resonance) and theoretical isotopic abundance mass distributions for one or more holoprotein charge states.

The Proposed Molecular Mechanisms Used by Archaea for Fe(III) Reduction and Fe(II) Oxidation

open access: yesFrontiers in Microbiology, 2021
Iron (Fe) is the fourth most abundant element in the Earth’s crust where ferrous Fe [Fe(II)] and ferric Fe [Fe(III)] can be used by archaea for energy conservation.

Studies on the Efficiency of Iron Release from Fe(III)-EDTA and Fe(III)-Cit and the Suitability of These Compounds for Tetracycline Degradation

open access: yesMolecules, 2022
Iron ions can be used to degrade tetracycline dispersed in nature. Studies of absorption and fluorescence spectra and quantum chemistry calculations showed that iron is more readily released from Fe(III)-citrate than from Fe(III)-EDTA, so Fe(III)-citrate

The role of green rust in the environment: a review O papel do green rust no ambiente

open access: yesRevista 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.

The role of gentisic acid on the Fe(III) redox chemistry in marine environments

open access: yes, 2021
Phenolic compounds excreted by marine microalgae are part of the ligand pool in natural waters. The effect of the polyphenol gentisic acid (GA; 2,5 dihydroxybenzoic acid) on the Fe(III) reduction as a function of organic ligand concentration (100 nM ...
