Gibbs energies of transfer of alkali metal cations between mutually saturated water-solvent systems determined from extraction experiments with radiotracer (super 137)Cs
Article Abstract:
A study was conducted to ascertain the linearities of Delta(sub t)(super 0 *)(M(super +) values on respective DeltaG(sub hydr)(super 0)(M(super +)'s which works well for either four cations Cs(super +) , Rb(super +) , K(super +) , and Na(super +) (nitrosolvents), or for three cations Cs(super +), Rb(super +), and K(super +). The findings suggest that the anomalies for Li(super +) and, to lesser extent for Na(super +) could be accounted for by excessive hydration of these ions in the water-rich organic phases.

Effective interaction potentials for alkali and alkaline earth metal ions in SPC/E water and polarization model of hydrated ions
Article Abstract:
The ion-ion distribution functions obtained from implicit-water Monte Carlo (MC) simulations of electrolyte solution with these potentials are explored. An improved model of ions include approximations of the ion hydration shell polarization and specific short-range ion-ion interaction, which allows approximation of the potential of mean force acting on ions in strong electric fields of highly charged macromolecules and bilayers.

Effective interaction potentials for alkali and alkaline earth metal ions in SPC/E water and prediction of mean ion activity coefficients
Article Abstract:
Molecular dynamics (MD) simulations are used to determine the effective ion-ion potentials between alkali and alkaline earth cations and a chloride anion in the extended simple point charge model (SPC/E) water. The effective potentials are used in implicit-solvent Monte Carlo (MC) simulations of electrolyte solutions to calculate ion activity coefficients at electrolyte concentrations between 0.1 and 1 M.
