The purpose of this work was to study the effect of variations in the interface tension between two immiscible liquids on the behavior of air bubbles that are formed in the lower phase, pass through the liquid/liquid interface, and the rise through the upper phase transporting an envolving layer.
The viscosity of the lower phase was maintained at 1.00c.c., and the upper at 0.45c.s. and the interface tension between the phases was varied from 5din/cm to 30din/cm. The diameter of bubbles had a variation from 2 to 10mm, with a large number of intermediary points.
Several photographic and measurement techniques were developed and tried before taking the data presented in the mass-transport curves.
The existence of an increase in range for which mass-transport exists and a decrease in the portion of liquid transported was found when the interfacial tension decreases.
