Notes:
Coupled diffusion generated countergradient transport through membranes is analyzed by experimental and theoretical means. Membrane wedge interferometer experiments on an ethanol—water-cellophane membrane system show that net countergradient mass transfer of the less permeable component ethanol may be generated over a wide concentration range. A theoretical analysis of an idealized membrane separating two binary bulk solutions is developed to display further the major features of diffusional coupling effects, and good agreement between observed and predicted countergradient transport characteristics is shown.
