HETEROCOALESCENCE BETWEEN DISPERSED ORGANIC MICRODROPLETS AND A CHARGED CONDUCTIVE INTERFACE

The Caselli-Lipollis-Gierst method of studying the heterocoagulation o f colloids at a plane mercury electrode has been extended to the inves tigation of the initial attachment and spreading of liquid organic dro plets dispersed in an aqueous environment. The first measurements of f ast current-time transients due to displacement of the interfacial cha rge by spreading droplets were performed in aqueous dispersions of org anic liquids of increasing polarity (pristane, hexadecane, 1-heptadece ne, squalene and methyl oleate).
