Abstract

Globular proteins uptake kinetics by hydrogels of oppositely charged network polyelectrolytes was studied with relation to the polyelectrolyte composition. It was shown that introduction of hydrophilic neutral units of acrylamide, inert towards proteins studied, significantly accelerated the uptake process, with no effect on the polyelectrolyte capacity towards proteins (with respect to ionic groups). The results obtained allow for optimization of the sorbent composition in order to enhance the polymeric pollutants uptake and/or tune their release rate.
