On the electrokinetic characterization of charged polymeric membranes by transversal streaming potential

• Charged polymeric membranes are characterized by transmembrane streaming potential. Polymeric membrane structure can be affected a pressure application. Sequential difference doesn´t affects surface charge. hydraulic permeability. The effect of on the electrokinetic properties different charged is analysed. Electrokinetic characterization involve application increasing or decreasing differences over sample. aim this work to study whether during measurement process determine zeta potential and intrinsic permeability causes irreversible change. It relevant issue in technology, because used analyse viability performance ion-exchange processes practical applications. We show that This influence does not affect charge distribution membranes, but it strongly structure.
