Abstract

Calculation of the thermodynamic characteristics of the interface of two immiscible electrolyte solutions is carried out by a statistical thermodynamic approach using the lattice model. The calculation is based on the self-consistent mean-field theory for adsorption and/or aggregation, developed at the Agricultural University of Wageningen, The Netherlands. The model parameters are chosen to describe the behaviour of liquid membrane ion-selective electrodes. The effect of solute ion concentration and lipophilicity on the potential difference is studied. Different electrode membrane compositions are modelled by selecting the concentrations of ion-exchange sites and neutral carrier molecules. The mathematical model presented in this paper has been found suitable for describing, at least qualitatively, some of the most important characteristics of liquid membrane ion-selective electrodes.
