Description

TOA dissolved in xylene was used as carrier, constituting liquid membrane supported in Celgard 2400 polypropylene microporous film for the transport of uranyl ions against their concentration gradient from aqueous solutions to an alkaline aqueous phase. Effect of stirring rate, nitric acid concentration and TOA concentration in the organic membrane phase, on the flux of uranyl ions through the membrane was studied. Viscosity and density data were obtained to estimate diffusion coefficients. Analysis of the flux data was performed to study the stoichiometry of the chemical reaction involved in complex formation reaction. The results are compared with simple liquid-liquid extraction data.
