Emulsified oil droplets in water are surrounded by negative zeta potential, and as a result, they move toward the positive electrode, when an electric potential is applied. This electrophoresis velocity of droplets was measured at various electric potentials, 1.569, 2.61 and 5.23 volts/cm, and various temperatures in the range from 71°F to 116°F. The measured electrophoresis velocity is in the range from 0.4 to 1.6 mm/min, depending upon the electric potential applied.
