Description

Verfahren zur Herstellung von Blausäure adsorbierenden Massen aus auf porösem Trägermaterial ausgefällten Carbonaten der Schwermetalle für Gas- und Atemfilter Es, ist bereits ein Verfahren zur Herstellung Blausäure adsorbierender Massen aus auf porösem Trägermaterial ausgefällten Carbonaten der Schwermetalle für Gas- und Atemfilter vorgeschlagen worden, bei dem man das poröse Trägermaterial zunächst mit einer Lösung eines oder mehrerer Schwermetallsalze tränkt, danach auf bzw. in dem Tränkungsprodukt durch Einbringen desselben in Alkalilauge od. dgl. Hydroxyde ausfällt und schließlich die so hergestellten Massen der Einwirkung eines Kohlensäure enthaltenden Gasstromes unterwirft. Es sind id'abei als Schwermetallsalze beispielsweise Chloride des Nickels, des Kobalts -und des Kupfers vorgeschlagen worden.Process for the production of hydrogen cyanide adsorbent masses Heavy metal carbonates precipitated on porous carrier material for gas and Respiratory filter There is already a process for the production of hydrogen cyanide adsorbing Masses of heavy metal carbonates precipitated on a porous carrier material has been proposed for gas and breathing filters, in which the porous carrier material first soaked with a solution of one or more heavy metal salts, then on or in the impregnation product by introducing it into alkali or the like. Hydroxides precipitates and finally the masses produced in this way under the action of a Subjected to carbonic acid-containing gas stream. They are there as heavy metal salts for example chlorides of nickel, cobalt and copper have been proposed been.

Die Erfindung betrifft eine weitere Ausbildung dieses Verfahrens. Die Erfindung besteht darin, daß die Schwermetallsalze in Form ihrer Sulfate zur Anwendung gebracht werden. Während, nämlich die Chloride besonders starke Neigungen zeigen, Korrosionen herbeizuführen, ist dies bei ,den Sulfaten nicht der Fall. Da als Behälter für die Atemfilter meistens. leicht korrodierendie Eisenbleche benutzt werden, ist die erfindungsgemäße Verwendung der Sulfate vorteilhaft.The invention relates to a further development of this method. The invention consists in that the heavy metal salts in the form of their sulfates for Can be applied. While, namely the chlorides particularly strong tendencies show that they cause corrosion, this is not the case with sulfates. There as a container for the respiratory filter mostly. the iron sheets used to corrode slightly the use of the sulfates according to the invention is advantageous.
