Separation properties of water/ethanol mixtures by acrylamide gel poly
merized repeatedly in the pores of silica - alumina thin membrane were
examined. By repeating the polymerization of gel, the flux of ethanol
decreases monotonously, while the permeation of water is promoted as
the flux of ethanol becomes sufficiently small. As a result, extremely
high separation performance can be obtained. The increment of water f
lux is closely related to the swelling degree of the gel in water, and
an optimum gel composition for the promotion of water permeation exis
ts.
