Abstract:
1. A continuous collection method of a particle component in an aqueous solution, comprising the steps of: introducing a particle component and a dissolved component in an aqueous phase into a top of a column part; spouting a solvent phase having hydrophobic nature and not mixing with water from a bottom of the column part, thereby generating an emulsion flow of the aqueous phase and solvent phase in the column part, wherein the particle component in the aqueous phase aggregates at a liquid-to-liquid interface using an aggregation phenomenon and the dissolved component in the aqueous phase is extracted into the solvent phase through the liquid-to-liquid interface; removing the solvent phase in an upper phase separation part coupled to an upper side of the column part; removing a clean aqueous phase from which particle component and dissolved component have been removed from a lower phase separation part coupled to a lower side of the column part; and collecting the particle component that has aggregated at the liquid-to-liquid interface within the column part.
