Sinopsis

In this paper are described the experimental investigations of the mass transfer processes of a fluorescent dye (rhodamine 6G) across an interface between two partially miscible liquids (water and 1-butanol) with an optical measurement technique, the laser induced fluorescence (LIF). The results of the experiments, the twodimensional concentration profiles, are measurable with a high spatial (110 μm) and temporal (25 ms) resolution. The concentration profiles across the interface do not correspond with those expected on basis of conventional theories. A distribution equilibrium at the interface could not be found and the concentrations are changing continuously from a minimum value in the aqueous phase to a maximum in the organic phase. Possible explanations of the observed phenomena are given.
