Co-oxidation of As(III) and Fe(II) by oxygen through complexation between As(III) and Fe(II)/Fe(III) species

Water Research, 2018
Previous studies have shown that the oxidation of Fe(II) by molecular oxygen can lead to the co-oxidation of As(III) at neutral pH. However, the mechanism of As(III) oxidation in the presence of Fe(II) with respect to the interaction between As(III) and Fe(II) is still unclear. In this work, we examined the oxidation of As(III) in the presence of Fe(II)

Photophysics of Fe(III)–tartrate and Fe(III)–citrate complexes in aqueous solutions

Chemical Physics Letters, 2012
Abstract Femtosecond pump–probe spectroscopy was used to determine the photophysical processes of Fe(III) complexes with citric and tartaric acids ([Fe(Cit)] and [Fe(tart)] + ) in aqueous solutions. The excitation of the complexes in the charge transfer bands is followed by formation of an intermediate absorbance decaying with two characteristic ...

Formation of ferrocyanides—III Fe(III), La(III) and Ce(III)☆

Talanta, 1973
Potassium ferrocyanide forms Fe(4)[Fe(Cn)(6)](3) with Fe(III), KLaFe(CN)(6) with La(III) and KCeFe(CN)(6) with Ce(III). The thermodynamic data for the two lanthanide compounds have been determined.

Adhesion of Dissimilatory Fe(III)-Reducing Bacteria to Fe(III) Minerals

Geomicrobiology Journal, 2002
The metabolism of dissimilatory iron-reducing bacteria (DIRB) may provide a means of remediating contaminated subsurface soils. The factors controlling the rate and extent of bacterial F(III) mineral reduction are poorly understood. Recent research suggests that molecular-scale interactions between DIRB cells and Fe(III) mineral particles play an ...

Removal of arsenite by Fe(VI), Fe(VI)/Fe(III), and Fe(VI)/Al(III) salts: Effect of pH and anions

Journal of Hazardous Materials, 2009
The removal of arsenate and arsenite from drinking water poses challenges, especially when arsenite is present in a significant amount. The removal of arsenite by K(2)FeO(4), K(2)FeO(4)/FeCl(3), and K(2)FeO(4)/AlCl(3) salts was studied at pH 6.5 and at an initial As concentration of 500 microg As(III)L(-1). The arsenite removal in Fe(VI)/Fe(III) and Fe(

Selective adsorption of apoferritin on immobilized Fe(III): demonstration of Fe(III) binding sites

Biotechnology and Applied Biochemistry, 1990
Immobilized metal ion affinity chromatography has been used to demonstrate and partially characterize Fe(III) binding sites on apoferritin. Binding of Fe(III) to these sites is influenced by pH, but not affected by high ionic strength. These results suggest that both ionic and coordinate covalent interactions are important in the formation of the Fe ...

Phosphopeptide Purification by IMAC with Fe(III) and Ga(III)

Cold Spring Harbor Protocols, 2007
INTRODUCTIONImmobilized metal ion affinity chromatography (IMAC) makes use of matrix-bound metals to affinity-purify phosphoproteins and phosphopeptides. Commonly used metals in early studies such as Ni2+, Co2+, Zn2+, and Mn2+ were shown to bind strongly to proteins with a high density of histidines.

The effects of Fe(III) and Fe(II) on anammox process and the Fe–N metabolism

Chemosphere, 2021
This study aims to compare the effects of different Fe stress on anammox (anaerobic ammonium oxidation) process, therefore seven identical reactors were operated under different Fe(II)/Fe(III) concentrations. After 38 days of operation, the anammox activity was highest (10.49 ± 0.41 mg-TN/(g-VSS·h)) under conditions of 5 mg/L-Fe(II), while under 30 mg ...
