Abstract
The multi-frequency laser interferometric method for measuring concentration profiles under electrodialysis with ion-exchange membranes including the case of small intermembrane distances and in the presence of ion-conducting spacers is developed. Experimental results obtained by laser interferometric method are in good agreement with the mathematical models of electrodialysis. The amplitude of the concentration field oscillations is shown to increase at the current density exceeding the limiting current density, and these oscillations transfer into the state of dissipative chaos. This instability is presumably a consequence of irregularly distributed heat sources, namely, the Joule heat and the heat of dissociation and recombination of water molecules.
