An experimental investigation of the electrokinetic phenomena known as primary electroviscous effect with suspensions of polystyrene spheres is described. A characteristic coefficient of the effect has been measured by an automatic method for the determination of the viscosity of liquids through capillary viscometers. In order to compare this coefficient with the values predicted by different theoretical models, the electrophoretic mobility of the spheres was measured by means of a microelectrophoresis apparatus. The zeta potential was calculated from the results with a complete theory of the electrophoresis of spherical particles. The comparison between theoretical and experimental values of the electroviscous effect shows that the theories of Booth and of Watterson and White reproduce very well the general trend of the experimental results, althogh they seem to underestimate the latter.

“…Bonincontro et af. 253 have found that k , and k2 in equation (45) are temperature dependent for 0.09 1 p polystyrene particles in 3.5 x lop4 M aqueous LiCl solution. On mixing charged particles of different types, theory254 and experiment237 indicate that there may be a considerable reduction in viscosity due to many body interparticle effects.…”

“…According to this author l, the electroviscous coefficient can be calculated using the following expression: ( (6 ) where Z(Ka) is a rather complicated function that can be * found in Booth's paper, and q can be written: (7 ) both summations extending to the total number of ions in solution. Here n~is the number concentration of the type i ions and Ai its drag coefficient.…”
