The Determination Of Liquid/Liquid Interfacial Mass Transfer - A New Application For The Analytical Ultracentrifuge

In recent years we have developed a new method for the determination of liquid/liquid interfacial mass transfer in solvent extraction systems by use of the Beckman Model E Analytical Ultracentrifuge (AUC). We improved both optical systems of the AUC by use of modern technical equipment like A/D converter, PC data handling, video recording and digitizing. Software has been developed with respect to the evaluation of kinetic data and a diffusion controlled solvent extraction model was applied for the determination of transfer coefficients.
