Title:
LIQUID-LIQUID EXTRACTING DEVICE AND LIQUID-LIQUID EXTRACTING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/168213
Kind Code:
A1
Abstract:
[Problem] To provide a liquid-liquid extracting method and a liquid-liquid extracting device that has a simple structure that does not require a driving unit and can process a large volume of a solution for extraction.
[Solution] A liquid-liquid extracting device that brings two liquids that are separated by an interface formed therebetween into contact and extracts a substance from one liquid into the other liquid, said liquid-liquid extracting device comprising an extracting unit (10) that has a plurality of extraction channels (10h) for passing two liquids (S, E), a liquid supplying unit (13) for supplying a liquid to the extracting unit (10), and a liquid discharging unit (14) for discharging the liquids (S, E) from the extracting unit (10). The extracting unit (10) is formed so that the cross-sectional area of the extraction channels (10h) changes in the direction of flow. Since the cross-sectional area of the extraction channels (10h) changes, the area of the interface between the two liquids flowing in the extraction channels (10h) can be changed, and a convective flow (CV) can be generated in each liquid. Thus, the extraction efficiency between the two liquid can be improved just by flowing the two liquids (S, E).
