 · Herein, we show that Bi 3+ drives the formation of aqueous Fe 3+ clusters, usurping the role of pH. We isolated and structurally characterized a Bi/Fe cluster, Fe 3 BiO 2 (CCl 3 COO) 8 (THF)(H 2 O) 2, and demonstrated its conversion into an iron Keggin ion capped by six Bi 3+ irons (Bi 6 Fe 13). The reaction pathway was documented by Xray ...

Effects of iron on arsenic speciation and redox chemistry ...

The results show that arsenic speciation is generally in equilibrium with iron chemistry in low pH AMD, which is often not the case in other naturalwater matrices. High pH mine waters and groundwater do not always hold to the redox predictions as well as low pH AMD samples. The oxidation and precipitation of oxyhydroxides deplete iron from some systems, and also affect arsenite and arsenate ...

THE ROLE OF IRON IN HEMOGLOBIN SYNTHESIS

In comparison with the preceding elegant chemistry, this discussion cannot help but seem both diffuse and obscure. Having made the obvious statement that iron is essential for heme formation and after a few random observations on the behavior of the cell in accomplishing this synthesis, I find that most of my own thinking on this subject extrapolates to hemoglobin production in the intact ...

Iron geochemistry in surficial sediments largely revolves around redox reactions involving Fe(III), primarily in solid phase oxides and oxyhydroxides (referred to here simply as iron oxides), and Fe(II), which is primarily found either dissolved in pore waters or, in the presence of sulfide, as either solid phase acid volatile iron .

06/09/2012 · Iron is an integral part of the natural environment and many important chemical reactions involve changes in iron that are caused by an electron being transferred to the iron from other minerals, water or biological agents. Electron transfer to iron III) oxides creates iron(II) sites in the mineral. But the iron(II) site is not fixed, as the electron can hop to other sites. Because iron(II) is ...
