    Notes: Abstract The hydrodynamic and osmotic terms in the relaxation field are computed up to order linear in concentration for a dilute solution of mixed strong electrolytes using the primitive model. The computation is based on the relative function μji computed in part earlier for the purely electrostatic interaction and in part in this work for the hydrodynamic interaction assuming the adequacy of the Fuoss velocity field. The results are compared with the earlier computations of Fuoss and Onsager, Murphy and Cohen, and Falkenhagen, Ebeling, and Kraeft. It is found that some terms of the new results are in agreement with the earlier computations and the other terms represent an improved computation.

    Conductance equation of dilute mixed strong electrolytes. III. Electrophoresis (1979)
    Springer
    Journal of solution chemistry 8 (1979), S. 509-518 
    Details
    ISSN: 1572-8927
    Keywords: Conductance equation ; mixed electrolytes ; electrophoresis ; ionic interactions ; solvent motion ; Poisson-Boltzmann equation ; electrolyte solution

    Notes: Abstract The electrophoretic velocity is computed through the order linear in concentration for a system containing any number of species of ions of any charges. The computation is based on the general theory of Fuoss and Onsager and the method for the generalization to mixed electrolytes developed by Chen and Onsager for the primitive model. The Boltzmann factor exp. (—ei Ψ ji/kT) is retained explicitly through the computation to obtain a result consistent with earlier computations of the relaxation field. The equilibrium potential including a correction to Poisson-Boltzmann equation is used, which adds a linear term ΔV j c to the electrophoretic velocity in agreement with the result of Murphy and Cohen. The correction to the ionic distribution due to the solvent motion is considered, which results in a linear term inversely proportional to the square of the viscosity of the solution. The main contribution is ΔV j E , which is in agreement with the result for symmetrical electrolytes of Falkenhagen et al. with only a slight difference due mainly to the different approximation used in the computation of the local force.
