Isotopic fractionation by diffusion in groundwater
During the last decade, isotopic fractionation has gained acceptance as an indicator of microbiological and chemical transformations of contaminants in groundwater. These transformation processes
Surfactant Diffusion Near Critical Micelle Concentrations
Taylor dispersion and differential refractometry are used to measure mutual diffusion coefficients (D) for binary aqueous solutions of octylglucopyranoside, dodecylsulfobetaine, and sodium dodecyl
Binary Diffusion Coefficients for Aqueous Solutions of Lactic Acid
Taylor dispersion equipment installed at the University of Coimbra for the measurement of diffusion in liquids has been tested to ensure adequate accuracy and precision by measuring mutual diffusion
Diffusion in aqueous copper sulfate and copper sulfate-sulfuric acid solutions
Diffusion coefficients of copper sulfate-water and copper sulfate-sulfuric acid-water solutions have been determined at 25°C using conductimetric and diaphragm-cell techniques. The ternary diffusion
Conductometric determination of the Soret coefficients of a ternary mixed electrolyte. Reversed thermal diffusion of sodium chloride in aqueous sodium hydroxide solutions
Une methode de conductimetrie est developpee pour determiner les coefficients de Soret d'une solution aqueuse d'hydroxyde de sodium et de chlorure de sodium
Activity coefficients and diffusion coefficients of dilute aqueous solutions of lithium, sodium, and potassium hydroxides
A simplified version of Harned's conductimetric technique has been used to measure binary diffusion coefficients of aqueous lithium, sodium, and potassium hydroxides at 25°C from 0.002 to 0.14
Diffusion in dilute aqueous acetic acid solutions at 25°C
A conductimetric technique has been used to measure diffusion coefficients for aqueous solutions of acetic acid at concentrations from 0.002 to 0.02 mol-dm−3 at 25°C. The acetic acid component
The unusual importance of activity coefficients for micelle solutions illustrated by an osmometry study of aqueous sodium decanoate and aqueous sodium decanoate + sodium chloride solutions.
Inflection points in the extent of micelle formation, used to calculate critical micelle concentration (cmc) lowering caused by added salt, provide unexpected thermodynamic evidence for the elusive second cmc.
Binary Mutual Diffusion Coefficients of Aqueous Cyclic Ethers at 25 °C. Tetrahydrofuran, 1,3-Dioxolane, 1,4-Dioxane, 1,3-Dioxane, Tetrahydropyran, and Trioxane
Taylor dispersion and differential refractometry are used to measure mutual diffusion coefficients (D) for the binary mixtures 1,4-dioxane + water, 1,3-dioxolane + water, and tetrahydrofuran + water
