Abstract

Investigation results of sorption of lisozyme by membranes based on poly-mphenylenisophthalamide,
co-polymers of m-phenylenisophthalamide of different composition with
sulfonate-containing fragment and mixtures of poly-m-phenylenisophthalamide with co-polymer
acrilonitrile with dimethyldiallylammonium chloride in static mode and under ultrafiltration condition
have been presented. It has been shown that the Coulomb forces are the dominant ones that define the
protein/membrane interaction in the given systems, but the contribution of hydrophobic interactions is
also sufficient. It is the repulsion of Coulomb forces in the system protein/membrane that can assure the
optimum compromise of such membrane properties as selectivity and permeability.
