Description

Verfahren zur Enteisenung von Alkali- und Erdalkalisulfidlösungen. Das Verfahren des Patents 411529 betrifft die Enteisenung von Ätzalkalilaugen durch Behandlung mit Metallen, die einen hohen Lösungsdruck besitzen und sich infolge ihrer chemischen Eigenschaften dem alkalischen System anzupassen vermögen, beispielsweise Zink oder Aluminium.Process for the de-ironing of alkali and alkaline earth sulfide solutions. The method of patent 411529 relates to the de-iron removal of caustic alkali solutions Treatment with metals that have a high solution pressure and as a result able to adapt their chemical properties to the alkaline system, for example Zinc or aluminum.

Es wurde nun gefunden, daß man auch Alkalisulfidlösungen und Erdalkalisulfidlösungen in dieser Weise enteisenen kann, indem man z. B. eine rohe Schwefelbariumlösung mit geringen Mengen von Zinkpulver erhitzt.It has now been found that alkali metal sulfide solutions and alkaline earth metal sulfide solutions can also be used can de-iron in this way by z. B. a crude sulphurous barium solution heated with small amounts of zinc powder.

Beispiel i.Example i.

5oo Teile Roh-Schwefelbarium in wäßriger Lösung werden mit o,5 Teilen Zinkpulver etwa 1/2 Stunde lang unter stetigem Rühren gekocht. Nach Abkühlung auf etwa 5oQ C wird die Filtration vorgenommen. Das Filtrat erweist sich als eisenfrei. Beispiel 2.500 parts of crude sulfur barium in aqueous solution are mixed with 0.5 parts Zinc powder cooked for about 1/2 hour, stirring constantly. After cooling down The filtration is carried out at about 50 ° C. The filtrate turns out to be iron-free. Example 2.

5oo Teile Roh-Schwefelbarium werden mit etwa 17oo Teilen Wasser ungefähr i/2 Stunde unter Umrühren gekocht. Nach Abkühlung der Masse auf 55° C setzt man o,5 Teile Zinkpulver hinzu, rührt tüchtig um und läßt die Masse weiter auf 5o° C abkühlen. Alsdann wird die Filtration vorgenommen. Das Filtrat ist eiseiJrei.500 parts of raw sulphurous barium are mixed with about 1,700 parts of water Boiled i / 2 hour while stirring. After the mass has cooled to 55 ° C., it is set 0.5 parts of zinc powder are added, the mixture is stirred vigorously and the mixture is allowed to rise to 50.degree cooling down. The filtration is then carried out. The filtrate is free from ice.
