Specific ion effects in colloidal and biological systems

Zusammenfassung

A review. During the last ten years significant progress was made in the understanding of specific ion effects. On the one hand new ideas about the origin of these effects came up, and on the other hand new exptl. techniques were developed so that now even the ion concn. profile near surfaces can be measured with some confidence. In the present review some of the most important new progresses are summarized and critically discussed, esp. in the context of colloidal and biol. systems.
