Kinetics of quartz dissolution in electrolyte solutions using a hydrothermal mixed flow reactor
Patricia M. Dove,David A. Crerar +1 more
TL;DR: A hydrothermal mixed flow reactor has been developed to study the reaction kinetics of a wide variety of mineral/solution systems as mentioned in this paper, which is used to measure the dissolution rates of quartz at near-neutral pH in 0.0 to 0.15 m solutions of NaCl, KCl, LiCl, MgCl2 over a temperature range of 100 to 300°C.
Journal ArticleDOI
Silica diagenesis; II, General mechanisms
TL;DR: Amorphous silica phases (opal-A) precipitate in nature due to the formation of dense colloids in supersaturated alkaline aqueous solutions with low relative concentrations of other ions as discussed by the authors.
Journal ArticleDOI
Migration of Radioactive Wastes: Radionuclide Mobilization by Complexing Agents
TL;DR: Analysis of ion exchange, gel filtration chromatography, and gas chromatographymass spectrometry analyses have demonstrated that ethylenediaminetetraacetic acid (EDTA), an extremely strong complexing agent commonly used in decontamination operations at nuclear facilities, is causing the low-level migration of cobalt-60 from intermediate-level liquid waste disposal pits and trenches in the Oak Ridge National Laboratory burial grounds.
Journal ArticleDOI
Dissolution at dislocation etch pits in quartz
TL;DR: The first experimental validation of etch pit formation theory under hydrothermal conditions was reported in this article, where several samples of quartz were etched at 300°C in etchams of controlled dissolved silica concentration in order to measure the critical concentration, Ccrit, above which dislocation etch pits would not nucleate on the quartz surface.
Journal ArticleDOI
Dissolution kinetics of strained calcite
Jacques Schott,Susan L. Brantley,David A. Crerar,Christophe Guy,M. Borcsik,Christian Willaime +5 more
TL;DR: In this paper, the authors measured the dissolution rate of calcite at a range of pH (4.5-8.3) and temperature (3-80°C) and showed that the rate enhancement increased with increasing pH and decreasing temperature.
