| Abstract: | The previous papers of the authors have shown that with modern theories of solution the extraction equilibrium distribution can be calculated by the thermodynamic models. If the ion-association and idssociation equilibrium do not occur in the aqueous phase, it is suitable to use Pitzer′s equation for the activity coefficients of the single electrolyte and to use Frank-Thomson diffuse lattice theory for the activity coefficients of the mixed electrolytes.... |
