Kristall und Technik, 1978
AbstractThe kinetics of dissolution have been expressed using a generalized dissolution rate equation which combines concentration driving force and area terms and thus enables large amounts of undersaturation to be used in experiments.

The Kinetics of Dissolution Revisited
Journal of Chemical Education, 2003An experiment analyzing the kinetics of dissolution of a solid with cylindrical geometry in water is presented. The dissolution process is followed by measuring the solid mass and its size parameters (thickness and diameter) as a function of time. It is verified that the dissolution rate follows the Nernst model.

Kinetics of surfactant dissolution
Current Opinion in Colloid & Interface Science, 2001While the equilibrium phase behaviour of surfactants has received much attention, kinetic phenomena such as those associated with surfactant dissolution have been relatively neglected. We review recent work which is relevant to this field, which includes experiments and simulation of nucleation and growth in surfactant systems, information on self and ...

Kinetics of montmorillonite dissolution
Chemical Geology, 2014Abstract Low molecular weight organic acids, ubiquitous in soils and sediments, play an important role in the alteration and weathering reactions as they enhance mineral dissolution rates. The dissolution rate of montmorillonite was measured in buffered oxalate solutions over a pH range from 3 to 8 and total oxalate concentrations of 0.1, 0.3 and 1.0

The kinetics of chlorite dissolution
Geochimica et Cosmochimica Acta, 2007Abstract A model for the dissolution of chlorite has been developed based on fast ligand assisted proton attack of the alumina tetrahedra within the alumina-silica lattice followed by slower dissolution of the remnant silica lattice. While the rate determining step is within the silica dissolution regime, the rate is a function of the H+ and Al3 ...

Investigation of dissolution kinetics for high rates of dissolution
Soviet Physics Journal, 1970A procedure was developed for investigating the dissolution of crystals that rub against a substrate with the solvent, whereby the process becomes significantly intensified. A theory of the method is presented. The kinetics of dissolution of azobenzene in alcohol at different rates of substrate motion, normal loads on the crystal, and temperatures is ...

The Kinetics of Smectite Dissolution
Mineralogical Magazine, 1994Little is known about the dissolution rate of smectite in general, and its dependence on the degree of saturation. Furrer et al. (1993) measured the dissolution rate of montmorillonite as a func t ion o f pH under ac id ic cond i t i ons . However, their AI and Si results were not stoichiometric.

Dissolution Kinetics of Uric Acid Calculi
Journal of Urology, 1984Dissolution of uric acid calculi was studied in vitro. Calculated rate constants were then applied to an in vivo situation. The time required for complete dissolution of a uric acid calculus in a patient on oral alkali therapy can be estimated. Sodium bicarbonate, acetylcysteine, [tris(hydroxymethyl)aminomethane] and [tris(hydroxymethyl)aminomethane]-E

Dissolution Kinetics of Soluble Nondisintegrating Disks
Journal of Pharmaceutical Sciences, 1977An equation describing the isotropical dissolution of soluble nondisintegrating disks was developed. It was equivalent to the cube root law only if the height and diameter of the disk were equal. The dissolution kinetics of sodium chloride disks were examined, using a beaker equipped with a centrifugal stirrer as the dissolution chamber. The fit of the

Dissolution Kinetics of Calcium Phosphate Coatings
Implant Dentistry, 1998Plasma spray and high velocity oxy-fuel (HVOF) techniques produce coatings with varying composition and amounts of amorphous and crystalline phases. For coatings containing greater amorphous phases, a higher release of calcium ions is evident when samples are placed in Hank's calcium-free balanced salt solutions.
