Water transport in porous and non-porous membranes

摘要: Abstract Osmotic water flow, giving the filtration coefficient, and diffusion of isotopic were measured in a number or membranes. It is shown that ratio, g , between osmotic self-diffusion flux, observed under forces equal magnitude, may serve as measure for mutual interaction molecules penetrating membrane, compared to with membrane constituents. High values found porous films. In liquid membranes, small but does not unity. Hence, through these organic liquids, water-water interactions are same order water-solvent interactions. one polymer polyethylacrylate, close one, would be expected molecular dilute solulion. cellulose acetate films, only slightly higher than an analogous (triacetine) indicating here transport essentially homogeneous phase.
