Abstract
A method for determination of parameters of a three-wire model and Lichtenecker model on the basis of experimental data of conductivity measurement for ion-exchange resins and equilibrium solutions is developed and experimentally tested. This method allows determining the required parameters using experimental points available for measurements on the basis of the minimum root-mean-square deviation. Verification of the method using our own experimental data and data from the literature allowed establishing that the three-wire model in the case of a solid-phase resin is practically devoid of the “solution-only channel“ and can be considered as a two-wire model.
