Abstract
The effects of electrolytes in aqueous two-phase systems are investiga ted. It is shown that macroscopic and molecular models give a consiste nt view of electrolytes at interfaces. The electrostatic potential dif ference Delta phi between coexisting phases is a common property at in terfaces even though the phases are strictly electroneutral and Delta phi can not be measured. It is shown how ilio can be quantified under controlled conditions. Additionally, a molecular picture is presented based on computer simulations. (C) 1998 Elsevier Science B.V. All righ ts reserved.
