Abstract

The heterogeneous nucleation and growth of aluminum (oxy)hydroxide films in aqueous environments can be controlled by the speciation of dissolved Al species and the charge and structure of underlying mineral surfaces. The structure of gibbsite films nucleated at the interface between the muscovite (001) surface and 1 mM AlCl₃ solutions was investigated here as a function of pH using in situ X-ray reflectivity. The growth of well-ordered gibbsite films was observed at pH between 3 and 4, even when the solutions were undersaturated with respect to gibbsite. The ordering of these gibbsite films likely resulted from the structural similarity (i.e., epitaxy) between the basal planes of gibbsite and muscovite. The gibbsite films formed on the muscovite surface dissolved more than two orders of magnitude faster than bulk gibbsite in pH 4 HCl solution, indicating that they can be described as a metastable phase. In contrast, no film growth was observed at pH between 9 and 12 where the solutions were supersaturated with respect to gibbsite. These results indicate that adsorption and accumulation of aqueous Al(III) species (i.e., Al³⁺ and AlOH²⁺ at acidic pH) is a critical step for the formation of secondary minerals on the negatively charged muscovite surface.

Gibbsite growth kinetics on gibbsite, kaolinite, and muscovite substrates: Atomic force microscopy evidence for epitaxy and an assessment of reactive surface area

Journal Article Nagy, K L ; Cygan, R T ; Hanchar, J M ; ... - Geochimica et Cosmochimica Acta

New experimental data for gibbsite growth on powdered kaolinite and single crystal muscovite and published data for gibbsite growth on gibbsite powders at 80 C in pH 3 solutions show that all growth rates obey the same linear function of saturation state provided that reactive surface area is evaluated for each mineral substrate. Identification of the growth phase as gibbsite was confirmed by rotating anode powder x-ray diffraction. Rates on kaolinite were determined using steady-state measured changes between inlet and outlet solutions in single-pass stirred-flow experiments. Rates on muscovite were determined by measuring the volume of precipitated crystals in imagesmore »« less

Epitaxial Growth of Gibbsite Sheets on the Basal Surface of Muscovite Mica

Journal Article Stubbs, Joanne E. ; Legg, Benjamin A. ; Lee, Sang Soo ; ... - Journal of Physical Chemistry. C

The growth of aluminum (oxyhydr)oxide films on the basal surface of muscovite mica is an excellent model system for studying mineral nucleation, growth, and reactivity. Using off-specular crystal truncation rod X-ray scattering, we have determined the atomic-scale epitaxial relationships between muscovite and monolayer overgrowths of a gibbsite-like material. Here, we observe that dioctahedral sheets of aluminum (oxyhydr)oxide grow in three structurally distinct domains, separated by antiphase boundaries. Vacancies in the dioctahedral sheets overlie either the silicate tetrahedra or the ditrigonal cavities of the underlying muscovite surface. High-resolution atomic force microscopy indicates lateral island sizes of ~10 nm separated by 1–2more »« less

Structural Characterization of Aluminum (Oxy)hydroxide Films at the Muscovite (001)–Water Interface

Journal Article Lee, Sang Soo ; Schmidt, Moritz ; Fister, Timothy T. ; ... - Langmuir

The formation of Al (oxy)hydroxide on the basal surface of muscovite mica was investigated to understand how the structure of the substrate controls the nucleation and growth of secondary phases. Atomic force microscopy images showed that solid phases nucleated on the surface initially as two-dimensional islands that were <= 10 angstrom in height and <= 200 angstrom in diameter after 16-50 h of reaction in a 100 mu M AlCl3 solution at pH 4.2 at room temperature. High-resolution X-ray reflectivity data indicated that these islands were gibbsite layers whose basic unit is composed of a plane of Al ions octahedrallymore »« less

Surface chemistry, rate laws and isotach plots

Conference Lasaga, A C ; Burch, T E ; Nagy, K L - Geological Society of America, Abstracts with Programs; (United States)

Recent work on water-rock interactions has been focused on the catalytic or inhibitory effects of temperature, pH, organic molecules and dissolved salts on the rates. These studies can only be understood if the dependence of the rates on the thermodynamic state of the dissolution/precipitation reaction is factored out. A general form of the rate law for heterogeneous mineral surface reactions is given. The pH dependence of the rate and the possible catalytic or inhibitory effects of other aqueous species in solution has been explicitly taken out and is kinetically quite distinct from the final term, f([Delta]G), which accounts for themore »« less
