It is shown that for ultraporous membranes with the sizes of porous channels r in the range 10–70 nm appreciable electroosmotic flows and a good agreement of electrokinetic potential values determined by three different methods are observed. It is established that for nanoporous (r < 10 nm) glass membranes change of electroosmotic flow velocity with time is due to the development of concentration polarization.}, title={Determination of electrokinetic potential of porous glasses by methods of streaming potential, electroosmosis and electrophoresis}, type={artykuł}, keywords={optyka, electrokinetic potential, electroosmotic flow}, }
