Permselectivity membrane
Webmembrane through which ethanol permeates more rapidly than water is expected. However, since the molecular radii of ethanol and water are 0.52 and 0.37, respectively, diffusion selectivity is water selective and therefore most of the polymeric membranes show water permselectivity and there are only a few ethanol permselective membranes.
