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.

本研究的目的是发展液/液界面深度剖面的原位分析方法。我们在薄层两相微电池中制备了液/液界面，并应用了一些新的界面处理方法。研究结果表明：(1)液/液界面垂直振动小于1μm；(2)无两亲性的金胶体（粒径为5 ~ 40nm）被吸附在液/液界面上聚集。(3)得到了存在于液/液界面及其附近的荧光藏红花O的扩散系数。
