Zusammenfassung:The invention relates to an installation for the analysis of extraction and transport through a liquid membrane, comprising an apparatus (A) for extraction and transport through a liquid membrane, which is made of a U-shaped glass tube having two side branches (1 and 2) wherethrough two aqueous phases circulate and at whose bottom part there is an organic solvent, the aqueous phases being supplied continuously from some reservoir vessels (7 and 8), through some overflow vessels (9 and 10) provided with some valves (11 and 12) and through some conduits (13 and 14) and then being independently mixed by means of some stirrers (3) driven by a motor (4) with measurable variable speed and continuously discharged through some connections (17 and 18) provided with valves (19 and 20) and graduated glass tubes (21 and 22), to some reservoir vessels (23 and 24), the phases being contacted by means of some circular interfaces (15 and 16). Invenţia se referă la o instalaţie pentru studiul extracţiei şi transportului printr-o membrană lichidă, alcătuită dintr-un aparat (A) de extracţie şi transport printr-o membrană lichidă, realizat dintr-un tub de sticlă, în formă de U, având două ramuri laterale (1 şi 2), prin care circulă două faze apoase şi la a cărui parte inferioară se află un solvent organic, fazele apoase fiind alimentate continuu, din nişte vase rezervor (7 şi 8), prin intermediul unor vase de prea-plin (9 şi 10), prevăzute cu nişte robinete (11 şi 12), şi a unor conducte (13 şi 14) şi apoi amestecate independent, cu ajutorul unor agitatoare (3) acţionate de câte un motor (4) cu turaţie variabilă măsurabilă şi evacuate continuu, prin nişte racorduri (17 şi 18) prevăzute cu robinete (19 şi 20) şi tuburi de sticlă gradate (21şi 22), în nişte vase rezervor (23 şi 24), contactarea fazelor având loc prin intermediul unor interfeţe circulare (15 şi 16). ŕ
