Gaseous reduction of iron oxides: Part III. Reduction-oxidation of porous and dense iron oxides and iron

Metallurgical Transactions, 1972
The internal reduction of high-grade granular hematite ore in hydrogen and carbon monoxide, and also the internal oxidation of porous iron granules in CO2-CO mixtures have been investigated. To assist the interpretation of the rate data for porous iron and iron oxides, rate measurements have been made also with dense wustite, previously grown on iron ...

Reductive denitrification using zero‐valent iron and bimetallic iron

Environmental Technology, 2009
A study of reductive denitrification of nitrate was conducted. Microscale zero-valent iron (ZVI) and palladium-coated iron (Pd/Fe) were used in the reduction of nitrate with variable pH. The solution pH was controlled by an auto controlling system instead of chemical buffers.

Research of Iron Reduction and the Iron Reductase Localization of Anammox Bacteria

Current Microbiology, 2014
The iron-reducing capability of anammox bacteria was examined in this study using Percoll purified anammox bacteria. Anammox bacteria could reduce Fe(III) to Fe(II) with organic matters as the electron donor. The activity of anammox iron-reducing process was dependent on different electron donor, acceptor and pH.

Iron Promoted Reduction of Chromate by Dissimilatory Iron-Reducing Bacteria

Environmental Science & Technology, 2000
Chromate is a priority pollutant within the U.S. and many other countries, the hazard of which can be mitigated by reduction to the trivalent form of chromium. Here we elucidate the reduction of Cr(VI) to Cr(III) via a closely coupled, biotic-abiotic reductive pathway under iron-reducing conditions.

Iron-Mediated Hydrazine Reduction and the Formation of Iron-Arylimide Heterocubanes

Inorganic Chemistry, 2011
The reaction of Fe(N{SiMe(3)}(2))(2) (1) with 1 equiv of arylthiol (ArSH) results in material of notional composition Fe(SAr)(N{SiMe(3)}(2)) (2), from which crystalline Fe(2)(μ-SAr)(2)(N{SiMe(3)}(2))(2)(THF)(2) (Ar = Mes) can be isolated from tetrahydrofuran (THF) solvent.

Iron-chelating agents and the reductive removal of iron from transferrin

Biochemical Pharmacology, 1980
Abstract 2-Formylpyridine thiosemicarbazone, a strong iron (II) and iron(III)-chelating agent, removed iron from transferrin only under reductive conditions. The reaction required a bicarbonate-labilizing anion such as nitrilotriacetate in order for reduction and release of iron to the thiosemicarbazone to occur.
