Abstract

A dynamic model is derived for simultaneous transport of multiple ions through anion exchange membranes based on an irreversible thermodynamics approach. This model accounts for the convective transport of the dissociated and undissociated species in the module channels, and the diffusion and migration across the boundary layers and membranes. The model is validated for Donnan dialysis recovery of different monoprotic carboxylic acids. Simulations are used to evaluate the potential enhancement of lactate fluxes under current load conditions, referred as Electro-Enhanced Dialysis operation. This model is a useful tool to understand the transport mechanism in such electrochemical system.
