Sorption by the polymeric sorbents based on crosslinked polystyrene

Abstract

The influence of the polymer matrix nature on the sorption properties of some cross-linked polyelectrolytes is analyzed. It is shown that the nature of the polymeric sorbents selectivity is associated with heterophase polymer gel structure. The effect of the amount of crosslinking agent, nature of polar groups and individual properties of some low molecular weight electrolytes on the selectivity of the sorbents are studied. It was shown that the obtained values of the distribution constants do not change their values when varying the concentration and composition of the solution. This property of polymeric sorbents may be used to separate solutes.
