Large single crystals of biotite and near endmember phlogopite were reacted with acidic Cr
(VI)-and Cr (III)-bearing solutions, at 24–27° C and 1 atm. After reaction of the micas with Cr …

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 …

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 …

Trivalent chromium is generally considered relatively insoluble in aqueous fluids and melts.
However, numerous counterexamples in nature indicate Cr (III) mobilization by aqueous …

The chemical composition and charge of the biotite near-surface, in contact with NaCl
bearing aqueous solutions at 25° C from pH 1 to 12, have been derived via zeta potential …

Experiments were performed herein to investigate the rates and products of heterogeneous
reduction of Tc (VII) by Fe (II) adsorbed to hematite and goethite, and by Fe (II) associated …

The adsorption of Cr (IH) was studied at pH 1, 2, 3, 4, 6, 8, and 10 on chlorite and kaolinite
and at pH 1, 2, 3, and 6 on illite. The amount of chromium adsorbed on chlorite varied from …

A spike in chromium (Cr) abundance above crustal background in iron formations post-
dating the Great Oxidation Event (ca. 2.5-2.3 billion years ago) has been suggested to reflect …

The interactions between Cr in aqueous solutions and phyllosilicates were studied to
determine:(a) the amount of Cr (VI) to Cr (III) reduction in aqueous solutions by Fe (II) …

Structural changes and surface oxidation state were examined following the reaction of
hematite (001),(012), and (110) with aqueous Fe (II). X-ray reflectivity measurements …
