Vm. Barragan et C. Ruizbauza, ON THE DEPENDENCE OF THE THERMAL MEMBRANE-POTENTIAL ACROSS CATION-EXCHANGE MEMBRANES ON THE MEAN TEMPERATURE, Journal of membrane science, 134(1), 1997, pp. 75-84
The thermal membrane potential across a cation-exchange membrane has b
een determined under different experimental situations. In all cases,
a clear linear dependence between the thermal membrane potential, Delt
a Psi, and the temperature difference between both external electrolyt
e solutions, Delta T, has been observed. ?he value of Delta Psi depend
s on the mean temperature, (T) over bar, of the membrane system, showi
ng a maximum value at a certain value of (T) over bar. Though the valu
e of Delta Psi for each (T) over bar is notably affected by the unstir
red solution layers adjoining the membrane surfaces, the above-mention
ed maximum has not been found to be a direct consequence of this effec
t.
