Spectroscopic evidence for interfacial Fe(II)-Fe(III) electron transfer in a clay mineral.
Interfacial electron transfer has been shown to occur between sorbed Fe(II) and structural Fe(III) in Fe oxides, but it is unknown whether a similar reaction occurs between sorbed Fe(II) and Fe(III)-bearing clay minerals. Here, we used the isotopic specificity of (57)Fe Mössbauer spectroscopy to demonstrate electron transfer between sorbed Fe(II) and structural Fe(III) in an Fe-bearing smectite...
متن کاملSorption of Aqueous Fe(ii) on Goethite Investigated with Stable Oxygen Isotopes
This thesis work is aimed at examining the oxygen atom mixing between common iron(III) oxides and Fe(II)aq solution during the sorption process. First, O labeled iron(III) minerals were used in batch sorption reactors to study the exchange of oxygen atom within the Fe(II)aq – iron(III) oxide system. Results showed a much lesser extent of oxygen mixing than reported Fe mixing from previous studi...
متن کاملSelenium adsorption to aluminum-based water treatment residuals.
Aluminum-based water treatment residuals (WTR) can adsorb water- and soil-borne P, As(V), As(III), and perchlorate, and may be able to adsorb excess environmental selenium. WTR, clay minerals, and amorphous aluminum hydroxide were shaken for 24 h in selenate or selenite solutions at pH values of 5-9, and then analyzed for selenium content. Selenate and selenite adsorption edges were unaffected ...
متن کاملModeling in situ iron removal from groundwater with trace elements such as As
The cyclic injection of oxygenated water in an aquifer may induce in situ iron removal from groundwater. During injection of aerated water, sorbed ferrous iron is displaced by cations, oxidized in the pore space, and precipitated as ferric iron oxyhydroxide. During pumping, ferrous iron is sorbed from groundwater on the exchange and sorption sites, and the breakthrough of dissolved iron is reta...
متن کاملOBSERVATOIRE DE GRENOBLE et LABORATOIRE DE GEOPHYSIQUE INTERNE ET TECTONOPHYSIQUE THESE Physics of natural nanoparticles – water interfaces: chemical reactivity and environmental implications
Precise structural studies of nano-crystalline minerals using diffraction techniques have been hindered by the broad diffraction peaks found in their diffraction patterns. In this thesis, I have applied molecular scale techniques such as High-Energy X-ray Diffraction and Molecular Dynamics simulations to study the structure and reactivity of two nano-minerals of important environmental signific...
