Abstract
Water-in-heptane emulsions were prepared containing 0.5 % by volume of Span 80 and water-in-benzene emulsions with 1 % of Span 85.
By measuring the centrifugation current, the electrokinetic mobility was determined for different concentrations of electrolytes (NaCl, BaCl2, Ce(N03)3, Na2SO4, and also HCl and KOH) in the aqueous phase.
The influence of the valency of the cations required a generalization of the equation for the electrokinetic mobility in the case of emulsions. This makes an evaluation of zeta potentials difficult.
