title: Effect of the Temperature on the Electroosmotic Permeability of a Cation-Exchange Membrane
abstract: The water electroosmotic flux, JV, through a cation exchange membrane has been measured as a function of the temperature, T, with various values of the electrolyte concentration and for different current densities. From these measurements the electroosmotic permeability, W, of the membrane has been determined under different experimental conditions. In the studied temperature range, 282 K </= T </= 308 K, a clear dependence of W on T was observed, so that, W decreases when T increases at the lowest values of T, whereas the opposite behavior occurs at the highest values of T. For this reason the (T, W) curves show a minimum in most of the studied cases. The position of this minimum as well as the value of the minimum of the electroosmotic permeability depends clearly on the concentration and the current density. Copyright 1997 Academic Press.
