| Outline of Final Research Achievements |
The “emulsion-flow” method, where the occurrence and disappearance of emulsion (a fine mixture of an aqueous and organic phases) is controlled by only solution sending, has attracted attention as an innovative new liquid-liquid extraction technique. On the other hand, there are a number of technical problems, i.e., a temporal rapid growth of emulsion cannot be suppressed, high-density aqueous phase is not sufficiently emulsified, contact time of the two liquid phases is insufficient in the case of low extraction rate, and solid components cannot be continuously removed.
All of the problems described above have been resolved in the present study and a newly improved structure has been completed. In addition, knowledge about “emulsion-flow” phenomenon acquired through this study will be linked to establishing the methodology to design mechanical structures of emulsion-flow apparatuses.
