“…Because the mobilities are rather low, the results are not suitable for testing the present theory. Next, we come to experiments of Mooney (15), Jordan and Taylor (31), and yon Stackelberg and Heindze (17). All these authors have used emulsions; there is some doubt as to whether emulsion droplets behave as rigid particles, but recent publications are reassuring on this point.…”

A new calculation of the relation between the electrophoretic mobility and the/--potential of a spherical colloid particle is presented. The model consists of a rigid, electrically insulating sphere surrounded by a Gouy-Chapman double layer. The appropriate differential equations (which account for both electrophoretic retardation and relaxation effect) have been solved without approximations on an IBM 704 computer.The theoretical assumptions and the basic equations ~re stated. A detailed account of the solutions of the equations is pub]ished elsewhere. The present paper contains the complete results. Comparison of these results with those of Overbeek ~nd of Booth shows that, %r high ~--potential ~nd 0.2 < ~a < 50, their approximations generally overestimate the relaxation effect. The application to practical cases (especially colloid particles in solutions of 1-1 electrolytes) is discussed extensively. Finally, the theoretical results are compared with experimental data published by others.

“…Zeta potential measurements of various hydrocarbon droplets in water have revealed that such droplets can acquire a substantial negative charge which varies with the pH of the system. The source of the negative drop charge is generally attributed to a preferential adsorption of hydroxide ions onto the surface (Jordan and Taylor, 1952;Taylor and Wood, 1957;Stachurski and Michalek, 1985). Related to this, Reddy and Fogler (1980) have shown that organicin-water emulsions can actually be substantially stabilized against Brownian coalescence merely by increasing the pH of the aqueous phase.…”
