| Research Abstract |
The purpose of the present study is the development of in situ analytical method for depth profile of liquid/liquid interface. We prepared liquid/liquid interfaces in a thin-layer two-phase microcell and applied some new methods to the interface. The results in the present study are as follows : (1) The vertical vibration of liquid/liquid interfaces was found to be less than 1μm. (2) Gold colloids (5-40nm in size), which had no amphipathic property, were adsorbed to liquid/liquid interface and were aggregated there. (3) Diffusion coefficient of fluorescent safranine O existing at and near the liquid/liquid interfaces was obtained.
