Abstract
This paper was roughly reviewed for the topically interesting adsorption phenomena of surfactants at various liquid interfaces. The interfacial phenomena were of adsorption at the interfaces of air water, monolayer-water (penetration), oil water, air with monolayer-oil-water. Complicated interfacial phenomena caused with mixed surfactants have been introduced to be capable of being analyzed by the combination of adsorption theory with the experimental data; i.e., negative adsorption of co-ions at the charged adsorbed surface, adsorption of complex ions present in mixed surfactants, penetrated adsorption into the insoluble monolayers. It was also emphasized that the synergetic phenomena taken place in mixed surfactant solution could be analyzed quantitatively in terms of the surface compositions determined as a function of bulk compositions.
