Abstract
Some aspects of direct ion transfer across water/1,2-dichloroethane ha ve been analyzed using a very simple model based on thermodynamic cons iderations. It was concluded that ion solvation by water molecules may occur in some particular cases in the organic phase, delivering an im portant contribution to the Gibbs free energy of ion transfer between the aqueous and the organic phase. In general terms, this particular t ype of transfer should be favored in the case of highly charged small ions at interfaces with a relatively low surface tension and a large d ifference between the reciprocal of the corresponding dielectric const ants.
