Journal ArticleDOI
The roles of natural organic matter in chemical and microbial reduction of ferric iron
TL;DR: Investigation of the Fe(III) reduction kinetics and capacity by three fractionated NOM subcomponents in the presence or absence of the dissimilatory metal reducing bacterium Shewanella putrefaciens CN32 indicates that NOM was able to reduce Fe( III) abiotically; the reduction was pH-dependent and varied greatly with different fractions of NOM.
Journal ArticleDOI
Chemical Reduction of U(VI) by Fe(II) at the Solid-Water Interface Using Natural and Synthetic Fe(III) Oxides
TL;DR: It is demonstrated that abiotic, Fe(II)-driven U(VI) reduction is likely to be less efficient in natural soils and sediments than would be inferred from studies with synthetic Fe(III) oxides.
Journal ArticleDOI
Kinetics and Mechanisms for Reactions of Fe(II) with Iron(III) Oxides
TL;DR: It is proposed that electron transfer from adsorbed Fe(II) to structural Fe(III) in hematite results in oxidation of Fe( II) to AFO on the surface of hematITE and that solid-phase contact among hematites, AFO, and structural Fe (II) produces magnetite (Fe3O4).
Journal ArticleDOI
Enhancement of biological reduction of hematite by electron shuttling and Fe(II) complexation.
TL;DR: Natural organic matter enhancement of the biological reduction of hematite by the dissimilatory iron-reducing bacterium Shewanella putrefaciens strain CN32 was investigated under nongrowth conditions designed to minimize precipitation of biogenic Fe(II).
Journal ArticleDOI
Effect of calcium on dissolution and precipitation reactions of amorphous silica at high alkalinity
TL;DR: In this article, the kinetics and products of silica glass dissolution are studied as a function of solution pH, temperature, and availability of calcium, and it was observed that dissolution rate versus time increases linearly with pH and reaches a maximum at pH = 14, with slower dissolution at higher alkalinities.
