Reevaluating concentration polarization: clarifying its meaning, genesis, and consequences Joan Montes de Oca and Juan J. de Pablo University of Chicago, USA
Concentration polarization (CP) has been a central topic in the literature on ionic transport and is consistently highlighted in discussions related to the performance of selective membranes. In this poster presentation, we aim to elucidate the ambiguities surrounding the concept, particularly in the context of charged nanoporous membranes with pore diameters well above the Debye length. Our study delves into the mechanisms that give rise to CP, its impact on membranes' behavior, and the reasons why it should not always be viewed as a limitation. Furthermore, we investigate the relationship between CP and ionic current rectification properties of bipolar membranes. By offering a renewed perspective on CP, we hope to promote a deeper understanding of its implications and potential applications in selective membrane technology.
