Influence of Gel Layers on Electrokinetic Phenomena: 2. Effect of Ions Interaction with the Gel Layer

摘要: Abstract The electroosmotic flow in a straight cylindrical capillary with porous gel layer on its wall is considered, taking into account an ion's interaction the layer. It shown theoretically that this substantially modifies electrokinetic phenomena and it possible to observe even absence of any fixed charge solid surface (ζ potential equals zero) inside In case, are strongly dependent electrolyte type. For example, electrophoretic motion particle covered such may occur opposite directions for different electrolytes. influence concentration type presence investigated.
