Description

Diaphragma für elektroosmotische Verfahren.Diaphragm for electro-osmotic processes.

Unterwirft man Gemische verschiedener Art zum Zwecke der Trennung zwischen zwei Diaphragmen der Elektroosmose, so ist es oft wichtig, in dem Gemisch bestimmte Konzentrationen gewisser Ionen, so z. B. eine bestimmte Reaktion (sauer, alkalisch oder neutral) zu erhalten. Bisher wurde dieser Zweck durch Anwendung ausgewählter Diaphragmen erreicht, die durch ihre Ladung auf die Abwanderung der verschiedenen Ionen einen regulierenden Einfluß ausüben. Subjects mixtures of various kinds for the purpose of separation between two diaphragms of electroosmosis, it is often important in the mixture certain concentrations of certain ions, e.g. B. a certain reaction (sour, alkaline or neutral). So far, this purpose has been selected through application Diaphragms reached by their charge on the migration of the various Ions exert a regulating influence.

Nach der vorliegenden Erfindung werden stark positive Diaphragmen benutzt, deren Ladung durch ihren Gehalt an Metallsuperoxyd bestimmt wird. Derartige Stoffe, wie z.B. Bleisuperoxyd, NickelsuperQxyd, Mangansuperoxyd u. dgl., nehmen gegen die wässerige Lösung eine Spannung von mehr als I Volt an, während die bisher üblichen positiven Diaphragmen, z.B. solche aus Korund, höchstens O, I Volt Spannung erreichen Man kann die metallsuperoxydhaltigen Diaphragmen entweder durch Pressen des reinen Materials herstellen oder aber unter Anwendung von Bindemitteln, wie z.B. Zement u. dgl. In accordance with the present invention, there are strong positive diaphragms used, the charge of which is determined by their content of metal superoxide. Such Take substances such as lead superoxide, nickel superoxide, manganese superoxide and the like against the aqueous solution a voltage of more than 1 volt, while the previously common positive diaphragms, e.g. those made of corundum, with a maximum voltage of 0.1 volts The metal superoxide-containing diaphragms can be reached either by pressing of the pure material or using binders, such as e.g. cement and the like

Die Verwendung der Diaphragmen kann beispielsweise bei der Elektroosmose von Gemischen, die neben Eiweiß Ammonsulfat enthalten, verwendet werden. Die Möglichkeit, mit den vorliegenden Diaphragmen eine neutrale Reaktion zu erhalten, verhindert die Koagulation des Eiweises. In diesem Falle haben selbst die am stärksten positiven, bisher in Gebrauch gewesenen Diaphragmen nicht genügt, um die rasche Abwanderung der NHs-Ionen sowie die Entstehung der sauren Reaktion hintanzuhalten. The diaphragms can be used, for example, in electroosmosis of mixtures which contain ammonium sulphate in addition to protein. The possibility, Obtaining a neutral reaction with the present diaphragms is prevented the coagulation of the protein. In this case, even the most positive, Diaphragms previously in use are not sufficient to prevent the rapid migration to prevent the NHs ions and the formation of the acidic reaction.

Dies tritt z. B. in manchen Fällen bei der elektroosmotischen Darstellung von Serumpräparaten ein; bisher war es nötig, unter solchen Umständen die Schwefelsäure durch chemische Umsetzung aus dem Präparat zu entfernen. Diesem überstand soll durch Anwendung von Diaphragmen, die ganz oder teilweise aus Mangansuperoxyd oder Bleisuperoxyd bestehen, abgeholfen werden. This occurs e.g. B. in some cases in the electroosmotic representation of serum preparations a; hitherto it was necessary to use sulfuric acid under such circumstances to be removed from the preparation by chemical conversion. This should survive Use of diaphragms made entirely or in part of manganese peroxide or lead peroxide exist, to be remedied.
