TL;DR: In this paper, it was shown from recent results based on the statistical mechanics treatment of ionic solutions that the notion of an equilibrium between free ions and paired ions which wasa priori introduced in the chemical model of Bjerrum is essentially correct.
Abstract: It is shown from recent results based on the statistical mechanics treatment of ionic solutions that the notion of an equilibrium between free ions and paired ions which wasa priori introduced in the chemical model of Bjerrum is essentially correct. The mass-action law which is deduced from such a model is indeed derivable from the more exact treatments of Mayer, Rasaiah, and Friedman starting directly from Hamiltonian models and without any assumptions as to the chemical structure of the ionic solute in the solution. The transformation relation from a primitive-model result to any short-range Hamiltonian model equation is given. It allows a simple mathematical treatment of experimental data for dilute solutions, the derivation of useful information on the Gurney solvation effects, and an interpretation of the multistep association concept.

TL;DR: Theoretical breakthrough curves for an ion exchange column are presented for the case where equilibrium constant based on mass action law is infinite and particle diffusion is the rate-controlling step.
Abstract: Theoretical breakthrough curves for an ion exchange column are presented for the case where equilibrium constant based on mass action law is infinite and particle diffusion is the rate-controlling step. An effect of the electric field caused by the difference in diffusivity of counter ions on the breakthrough curves is evaluated by applying the Nernst-PIanck equation. Approximate equations are proposed for breakthrough curves whose maximum error from the exact solution is 4%. The theoretical values agree fairly well with experimental results in the R-H-NaOH system (equilibrium constant is infinite) and the R-Na-Ce(NO3)3 system (equilibrium constant is finite), respectively.
