Heterogeneous Anion-Exchange Membranes with Enhanced Ion Conductivity for Continuous Electrodeionization

open access: yesMembranes, 2023
In this study, the optimal fabrication parameters of a heterogeneous anion-exchange membrane (AEM) using an ionomer binder are investigated to improve the performance of continuous electrodeionization (CEDI) for producing ultrapure water.

Mathematical modelling of vortex structures in the channel of an electrodialysis cell with ion-exchange membranes of different surface morphology

open access: yesКонденсированные среды и межфазные границы, 2022
One of the ways to obtain membranes with electroconvection as the dominant mechanism of ion transport is to optimise the surface of known brands of commercial heterogeneous membranes by changing their manufacturing technology.

Stability of Ion Exchange Membranes in Electrodialysis

open access: yesMembranes, 2022
During electrodialysis the ion exchange membranes are affected by such factors as passage of electric current, heating, tangential flow of solution and exposure to chemical agents. It can potentially cause the degradation of ion exchange groups and of polymeric backbone, worsening the performance of the process and necessitating the replacement of the ...
