Application of a Theory of Binary Solution Surface Tension to Interfacial Tension Phenomena

摘要

A theoretical equation which describes interfacial tension of binary solutions as a function of concentration, and of the interfacial tensions and the molecular areas of the pure components has been applied to organic and aqueous systems against water and mercury. The derived equation gives information as to molecular area and orientation of adsorbed molecules at an interface. Gibbs' equation, while applicable to all interfaces, generates no detailed structural information. The derived equation is useful for determining the interfacial structure of solutions approximating its theoretical model. (Author)
