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…
