Ionic Transport Processes: in Electrochemistry and Membrane Science
Kyösti Kontturi, Lasse Murtomäki, and José A. Manzanares
Abstract
Modelling of heterogeneous processes, such as electrochemical reactions, extraction, or ion-exchange, usually requires solving the transport problem associated with the process. Since the processes at the phase boundary are described by scalar quantities and transport quantities are vectors or tensors, the coupling of them can take place only via conservation of mass, charge, or momentum. In this book transport of ionic species is addressed in a versatile manner, emphasizing the mutual coupling of fluxes in particular. Treatment is based on the formalism of irreversible thermodynamics, i.e., o ... More
Modelling of heterogeneous processes, such as electrochemical reactions, extraction, or ion-exchange, usually requires solving the transport problem associated with the process. Since the processes at the phase boundary are described by scalar quantities and transport quantities are vectors or tensors, the coupling of them can take place only via conservation of mass, charge, or momentum. In this book transport of ionic species is addressed in a versatile manner, emphasizing the mutual coupling of fluxes in particular. Treatment is based on the formalism of irreversible thermodynamics, i.e., on linear (ionic) phenomenological equations, from which the most frequently used Nernst-Planck equation is derived. Limitations and assumptions made are discussed in detail. The Nernst-Planck equation is applied to selected problems at the electrodes and in membranes. Mathematical derivations are presented so that the reader can learn the methodology of solving transport problems. Each chapter contains a large number of exercises.
