Electrokinetic measurements on concentrated polystyrene dispersions and their theoretical interpretation

Calculation of Zeta Potential from Electrokinetic Measurements on Titania Plugs

“…2) it should be noted that similar higher -potential values, obtained from conductivity measurements of polystyrene latex plugs (13,16), are reported in the literature (10,13), in comparison with the -potential values obtained from streaming potential measurements (13,17,18).…”

The Influence of a Dynamic Stern Layer on the Primary Electroviscous Effect

“…In their theory of electrophoresis, O'Brien and White (11) found a similar result plotting electrophoretic mobility against . Many papers on the electrokinetics of polystyrene latexes (12)(13)(14)(15)(16)(17)(18)(19) have proven that the standard electrokinetic model cannot explain the observed behavior. Zukoski and Saville (20) presented extensive experimental results on the electrophoretic mobility and electrical conductivity and found that the -potentials inferred from the suspension conductivity were larger than those derived from electrophoresis.…”

“…(28). The expression for S i 0 is [14] where N i is the total number of Stern layer sites per unit area and K i is the dissociation constant in the Stern layer for i ions. The problem we must solve is to obtain the solutions (F (x) and i (x)) of Eqs.…”

Estimation and comparison of ζ‐potentials of silica‐based anion‐exchange type porous particles for capillary electrochromatography from electrophoretic and electroosmotic mobility

“…A main restriction is that surface conduction is ignored. This effect might be more relevant for low electrolyte concentrations, because for relatively high concentrations bulk conductivity most probably dominates [15]. Under the present conditions, where the salt concentration is 10 22 mol/L, we assume that most probably surface conduction will not bias the z-potential determination.…”
