Verfahren zur Darstellung, Isolierung und Anreicherung von Radium und anderen radioaktiven Stoffen.
Vorliegende Erfindung bezieht sich auf eine Ausführungsform des Verfahrens zur Darstellung, Isolierung und Anreicherung von Radium und anderen radioaktiven Stoffen durch Adsorption aus Lösungen gemäss Stammpatent Nr. 58190 vermittelst Mangansuperoxyd und besteht darin, dass nach erfolgter Adsorption der radioaktiven Substanz an gefälltem Mangansuperoxydhydrat das adsorbierte Metall durch Anwendung eines geeigneten Lösungsmittels, wie z.
B. 1/10- bis 1/1-normaler heisser Salz- oder Salpetersäure gelöst wird, während das ungelöst zurückbleibende Adsorbens zu erneuter Verwendung regeneriert werden kann. Neben einer Ersparnis an Material hat dieses Verfahren gegenüber der Verflüchtigung des Adsorbens nach Stammpatent Nr. 58190 den Vorteil, dass es leicht zur systematischen ,,fraktionierten Adsorption" benutzt werden kann, wobei kleine Radiummengen, die in dem Mangansuperoxydhydrat zurück- geblieben sein könnten, stets wieder in den Prozess zurückkehren und nicht verloren gehen.
Das Verfahren ist besonders wertvoll in der Anwendung auf Lösungen, welche neben Radium noch Barium enthalten. Das Mangansuperoxydhydrat besitzt nämlich die Eigen8 ('haft. Radium in bestimmtem höherem Masse zu adsorbieren als Barium, so dass durch wiederholte Verwendung bestimmter Mengen von Mangansuperoxydhydrat als Adsorbens unter Auflösung des bei jedem Arbeitsgange adsorbierten Radiums und Bariums und Wiederverwendung der so gewonnenen Lösung zur Adsorption allmählich der Bariumgehalt des Radiums oder seiner Lösung auf''im'n geringen Bruchteil des ursprünglichen Bariumgehaltes herabgesetzt werden kann.

Process for the preparation, isolation and enrichment of radium and other radioactive substances.
The present invention relates to an embodiment of the method for the preparation, isolation and enrichment of radium and other radioactive substances by adsorption from solutions according to parent patent no. 58190 mediates manganese superoxide and consists in that after adsorption of the radioactive substance on precipitated manganese superoxide hydrate, the adsorbed metal Use of a suitable solvent, such as.
B. 1/10 to 1/1 normal hot hydrochloric or nitric acid is dissolved, while the undissolved adsorbent remaining can be regenerated for reuse. In addition to saving material, this method has the advantage over volatilization of the adsorbent according to parent patent no. 58190 that it can easily be used for systematic "fractional adsorption", with small amounts of radium that could have remained in the manganese peroxide hydrate go back into the process and not get lost.
The method is particularly valuable when applied to solutions which contain barium in addition to radium. The manganese peroxide hydrate has the property of adsorbing radium to a certain extent higher than barium, so that by repeated use of certain amounts of manganese peroxide hydrate as adsorbent, the radium and barium adsorbed in each operation are dissolved and the solution thus obtained is gradually reused for adsorption the barium content of the radium or its solution can be reduced to a small fraction of the original barium content.

one such manganese salts, which, such as. B.

and that only one and the same operation has to be carried out repeatedly, which results in a great simplicity of the working arrangements.
The implementation of the invention can be seen in more detail from the following examples.
