DYNAMIC PROCESSES OCCURRING AT THE CRIIIAQ-MANGANITE (γ-MNOOH) INTERFACE: SIMULTANEOUS ADSORPTION, MICROPRECIPITATION, OXIDATION/REDUCTION, AND DISSOLUTION

Weaver R.M.; Hochella M.F.; Ilton E.S. (2002)

The complex interaction between CrIIIaq and manganite (γ-MnOOH) was systematically studied at room temperature over a pH range of 3 to 6, and within a concentration range of 10-4 to 10-2 M CrOH2+aq. Solution compositional ...
HETEROGENEOUS REDUCTION OF URANYL BY MICAS: CRYSTAL CHEMICAL AND SOLUTION CONTROLS

Ilton E.S.; Haiduc A.; Moses C.O.; Heald S.M.; Elbert D.C.; Veblen D.R. (2004)

This contribution primarily uses X-ray photoelectron spectroscopy (XPS) to better understand mechanisms for coupled sorption-reduction of aqueous UVI by ferrous micas. Additional information was obtained with X-ray absorption ...
QUANTITATIVE DETERMINATION OF THE OXIDATION STATE OF IRON IN BIOTITE USING X-RAY PHOTOELECTRON SPECTROSCOPY: I. CALIBRATION

Raeburn S.P.; Ilton E.S.; Veblen D.R. (1997)

X-ray photoelectron spectroscopy (XPS) analyses of Fe(III)ΣFe were calibrated with nine single crystals of biotite of known Fe(III)ΣFe content. Peak shape parameters for the component Fe2+ and Fe3+ Fe 3p peaks were obtained ...
QUANTITATIVE DETERMINATION OF THE OXIDATION STATE OF IRON IN BIOTITE USING X-RAY PHOTOELECTRON SPECTROSCOPY: II. IN SITU ANALYSES

Raeburn S.P.; Ilton E.S.; Veblen D.R. (1997)

X-ray photoelectron spectroscopy (XPS) was used to determine Fe(III)ΣFe in individual biotite crystals in thin sections of ten metapelites and one syenite. The in situ XPS analyses of Fe(III)ΣFe in biotite crystals in the ...
THE CATALYTIC EFFECT OF SODIUM AND LITHIUM IONS ON COUPLED SORPTION-REDUCTION OF CHROMATE AT THE BIOTITE EDGE-FLUID INTERFACE

Ilton E.S.; Veblen D.R.; Moses C.O.; Raeburn S.P. (1997)

Large single crystals of biotite and near-endmember phlogopite were reacted with aqueous solutions bearing 20 μM Cr(VI) and different concentrations of NaCl, LiCl, RbCl, CsCl, NaClO4, and Na2SO4. Solutions were maintained ...
THE INFLUENCE OF STRUCTURAL FLUORINE ON BIOTITE OXIDATION IN COPPER-BEARING, AQUEOUS SOLUTIONS AT LOW TEMPERATURES AND PRESSURES

Earley D.; Dyar M.D.; Ilton E.S.; Granthem A.A. (1995)

High-F (5.4 wt%) and low-F (0.8 wt%) biotites were reacted with aqueous (Cu, Na2)Cl2 solutions at ambient conditions to investigate biotite oxidation mechanisms at low temperatures and pressures and at atmospheric pO2. The ...
USING X-RAY PHOTOELECTRON SPECTROSCOPY TO DISCRIMINATE AMONG DIFFERENT SORPTION SITES OF MICAS: WITH IMPLICATIONS FOR HETEROGENEOUS REDUCTION OF CHROMATE AT THE MICA-WATER INTERFACE

Ilton E.S.; Moses C.O.; Veblen D.R. (2000)

This contribution uses Cr2p and 3p binding energies (BEs) determined by X-ray photoelectron spectroscopy (XPS) to distinguish CrIII sorbed to different mica sorption sites. The results were used to better understand ...
X-RAY PHOTOELECTRON SPECTROSCOPIC MEASUREMENT OF THE TEMPERATURE DEPENDENCE OF LEACHING OF CATIONS FROM THE ALBITE SURFACE

Chen Y.; Brantley S.L.; Ilton E.S. (2000)

Polished albite single crystals were dissolved in flow or semi-batch reactors containing solutions at pH 2.9+/-0.1 at 5°, 50°, and 90°C until steady state dissolution was achieved. At steady state, all effluent solutions ...
