Abstract

A systematic study of the influence of exchange of ions on
the surface of silver iodide precipitates on the elektrokinetic
potential (EKP) was undertaken. Examples of the exchange o:f
ions of valencies 1 :2, 1 :3, 1 :4, 2 :4 and 3 :4 are given. At higher
activity of potential determining ions in solution, at pl= 3, larger
changes in the EKP were measured. At the same pl effects of specific
adsorption o:f Th4+ were found. The conclusion is drawn, that
the exchange of ions at the surface bears no direct, simple relation
to the EKP.
