Description
In der Patentschrift 629 6I7 ist ein Verfahren zur dialytischen Extraktion von Pflanzenstoffen beschrieben, nach dem die dialytischen Vorgänge an den semipermeablen Membranen der zu extrahierenden Pflanzen dadurch beschleunigt werden, daß man das Lösungsmittel dem Durchgang eines extrem niederperiodischen Stromes unterwirft, dessen Frequenz nur etwa 0,5 bis 5 Hz beträgt.In the patent specification 629 6I7 is a method for dialytic extraction described by plant substances, according to which the dialytic processes on the semipermeable Membranes of the plants to be extracted are accelerated by the Subjects the solvent to the passage of an extremely low-period current, whose frequency is only about 0.5 to 5 Hz.
Die Durchführung des Verfahrens erfolgte dabei etwa gemäß Abb. I in einem Perkolator 1, der eine Stabelektrode 2 und eine konzentrische Zylinderelektrode 3 enthielt und der mit den zerkleinerten Drogen in alkoholischer Lösung gefüllt wurde. Um das Perkolationsgut 4 dem Durchgang eines Wechselstromes von 0,5 bis 5 Hz zu unterwerfen, wurde die Batterie 5 unter Zwischenschaltung des rotierenden Polwenders 6 an die Elektroden 2, 3 gelegt.The procedure was carried out roughly as shown in Fig. I in a percolator 1, a rod electrode 2 and a concentric cylinder electrode 3 and the one filled with the crushed drugs in alcoholic solution became. To the percolation material 4 the passage of an alternating current of 0.5 to 5 Subject to Hz, the battery was 5 with the interposition of the rotating Pole inverter 6 placed on the electrodes 2, 3.
Die Wirkung des beschriebenen Verfahrens beruht wahrscheinlich darauf, daß an der semipermeablen Membrane Polarisationserscheinungen von periodisch wechselnder Richtung entstehen, die eine mikroskopisch-mechla nische Massage der Membran hervorrufen und hierdurch Verstopfungen der Membran entgegenwfrken. Infolgedessen bleibt die Membran dauernd voll durchlässig, und es läßt sich sowohl eine Verkürzung der Extraktionszeit als auch eine Steigerung der Ausbeute erzielen. The effect of the procedure described is probably based on that on the semipermeable membrane polarization phenomena of periodically changing Direction emerge, which cause a microscopic mechanical massage of the membrane and thereby prevent blockages in the membrane. As a result, the The membrane is permanently fully permeable and the extraction time can be shortened as well as an increase in the yield.
Gemäß der vorliegenden Erfindung wird die Anwendung des beschriebenen Verfahrens auf die Durchführung von dialytischen Trennungsvorgängen aller Art ausgedehnt, bei denen in an sich bekannter Weise eme zusammenhängende Membran vorgesehen ist. In accordance with the present invention, the application of the described is made Procedure extended to the implementation of dialytic separation processes of all kinds, in which a coherent membrane is provided in a manner known per se.
Es hat sich gezeigt, daß die dem Verfahren zugrunde liegenden rein physikalischen Wirkungen völlig unabhängig davon sind, ob die jeweils verwendeten semipermeablenMIembranen im Ausgangsmaterial enthalten sind oder ob sie einen Bestandteil der Apparatur bilden. Wesentlich ist nur, daß die Membranen selbst von Wechselstrom durchflossen werden, damit an ihnen Polarisationserscheinungen wechselnder Richtung und damit periodische Druckschwankungen von einer Frequenz auftreten, der die Elemente der Membran mechanisch noch zu folgen vermögen.It has been shown that the underlying purely physical effects are completely independent of whether each is used semipermeable membranes are contained in the starting material or whether they are a component of the apparatus. It is only essential that the membranes themselves be powered by alternating current are traversed, so that polarization phenomena of alternating direction on them and thus periodic pressure fluctuations of a frequency occur that the elements able to follow the membrane mechanically.
Eine Anordnung zur Durchführung des erfindungsgemäßen Verfahrens zeigt Abb. 2. An arrangement for carrying out the method according to the invention Fig. 2 shows.
Diese stellt einen Dialysator üblicher Art dar, der aus einem Trog 7 besteht, in den ein Membranbeutel 8 eingetaucht ist. Der Trog 7 enthält das Diffusat, der Beutel 8 das Dialysat. In das Dialysat ist erfindungsgemäß die Stabelektrode 9, in das Diffusat die Ringelektrode 10 eingetaucht. An die beiden Elektroden 9 und 10 wird die in entsprechender Weise wie in Abb. 1 erzeugte niedrigperiodische Wechselspannung gelegt.This represents a dialyzer of the usual type, which consists of a trough 7 consists in which a membrane bag 8 is immersed. The trough 7 contains the diffusate, the bag 8 the dialysate. According to the invention, the stick electrode is in the dialysate 9, the ring electrode 10 is immersed in the diffusate. To the two electrodes 9 and 10 becomes the low period generated in a manner similar to that in FIG AC voltage applied.
