| Titre : | Electrochemistry of the membrane/solution interface and mass transport phenomena through ion exchange membrane | | Type de document : | document multimédia | | Auteurs : | Abdallah Timmaoui, Auteur ; Mahmoud Ferhat, Directeur de thèse | | Editeur : | Laghouat : Université Amar Telidji - Département des sciences de la matière | | Année de publication : | 2025 | | Importance : | 75 p. | | Accompagnement : | 1 disque optique numérique (CD-ROM) | | Note générale : | Option : Surface chemistry and corrosion | | Langues : | Anglais | | Mots-clés : | Ion exchange membrane Mass transport Limiting current density Concentration polarization Overlimiting region | | Résumé : | The electrochemical behavior of ion-exchange membranes is governed by complex interactions at the membrane-solution interface, influencing ion transport, concentration polarization, and overlimiting phenomena. A deeper understanding of these processes is essential for optimizing membrane-based technologies such as electrodialysis and energy storage.
In this study, we investigate these phenomena using Linear Sweep Voltammetry (LSV), Chronopotentiometry (CP), and Electrochemical Impedance Spectroscopy (EIS). The effects of electrolyte concentration and ion nature on the current-voltage characteristics of ion-exchange membranes are analyzed, along with the influence of weak electrolytes and buffer solutions on mass transport mechanisms. The findings offer new insights into ion transport dynamics, helping to refine theoretical models and improve the performance of ion-exchange membranes in electromembrane applications. | | note de thèses : | Thèse de doctorat en chimie |
