Beschreibung
Zusammenfassung:The invention relates to a process for capturing and/or detecting at least one chemical element comprising the following steps: a) a liquid phase L is prepared comprising at least: - an amine; - a sample comprising at least one chemical element chosen from the group comprising post-transition metals, alkaline-earth metals, actinides, rare-earth elements, transition metals, and the combination thereof; - optionally a solvent; b) the liquid phase L is bought into contact with a gaseous phase G advantageously comprising CO2, under conditions that lead to the formation of a segmented flow, so as to form a third phase that concentrates said chemical element, referred to as "concentrated phase" in suspension in a stock solution; c) the concentrated phase is separated from the stock solution. The invention also relates to the use of this process and also to a facility for the implementation thereof.
