R. Andreu et al., GENERALIZATION OF THE UDCA THEORY AND ITS APPLICATION TO THE ANALYSISOF THE ION-FREE LAYER THICKNESS, Journal of electroanalytical chemistry [1992], 358(1-2), 1993, pp. 49-62
The modified Gouy-Chapman theory with two planes of closest approach i
s generalized for any electrolyte stoichiometry, considering also the
influence of the interfacial dielectric constant. Application is made
to some experimental systems to derive the cation and anion distances
of closest approach from the ion-free layer thickness.
