Verwendung von porösem Trägermaterial zum Adsorbieren von Blausäure.
Es ist bekannt, als Bindemittel für Blausäure basisches Zinkkarbonat oder andere basische Metallsalze, walche auf Trägermaterial, z. B. Kieselgur, aufgebracht sind, zu verwenden, doch haben derartige Mittel nur geringe Leistungsfähigkeit.
Es hat sich gezeigt, dass die Leistungsfähigkeit eines Blausäurefilters auf mehr als das Dreifache erhöht wird, wenn man das poröse Trägermaterial, insbesondere aktivierte Kohle oder anorganische Gele oder Gemische dieser Stoffe, zunächst mit einer Lösung von Kupfersalzen für sich oder in Mischung mit Kobaltsalzen oder/und Nickelsalzen tränkt und auf und in dem Tränkungsprodukt, z. B. durch Einbringen desselben in Alkalilauge, die basischen Salze bzw. Hydroxyde ausfällt. Dabei ist es vorteilhaft, wenn man die so hergestellte Masse der Einwirkung eines 002 enthaltenden Luftstromes unterwirft.
Träger der hier benutzten Art in der angegebenen Weise mit basischen Salzen bzw. Hydroxyden zu beschicken, ist gleichfalls bekannt, doch hat man bisher nicht erkannt, dass derart behandelte Körper ein hohes Bindevermögen für Blausäure besitzen.
In der Verwendung solchen nach oben beschriebener Art behandelten Trägermaterials ? ur Bindung von Blausäure ist die Erfindung zu erblicken.
Bei der Behandlung des Trägermaterials geht man z. B. so vor, dass man dieses mit der Lösung eines Kupfersalzes, z. B. CuCl2 und/oder CoCI2, tränkt. Dann bringt man das Produkt in eine Lösung von Alkalihydrdxyd, z. B. NaOH. Dadurch wird in den Poren des Trägers Metallhydroxyd, also Cu (OH) 2 und/oder Co (OH) 2 gefällt. Das Fällungsprodukt haftet fest an dem Träger. Darauf trocknet man die Masse ohne Anwendung von Hitze in einem trockenen Luftstrom, dem zweckmässig etwas (bis zu 5%) CO2 zugesetzt ist. Dadurch wird das Hydroxydgemisch in steigendemMasse in basisches Carbonat, z. B. CuOHCOg und CO2 (OH) 2COa, übergeführt, ein Vorgang, der in freier Luft mit der Zeit auch stattfinden würde.
Auf diese Weise wird erreicht, dass das Präparat im Filter und bei der Beatmung kein CO2 mehr aufnimmt, also nicht mehr"altert".

Use of porous carrier material to adsorb hydrogen cyanide.
It is known as a binder for hydrocyanic acid basic zinc carbonate or other basic metal salts, walche on carrier material, eg. B. kieselguhr, are applied, but such agents have only poor performance.
It has been shown that the efficiency of a hydrocyanic acid filter is increased more than threefold if the porous carrier material, in particular activated carbon or inorganic gels or mixtures of these substances, is initially mixed with a solution of copper salts or mixed with cobalt salts or / and nickel salts impregnate and on and in the impregnation product, e.g. B. by introducing the same in alkali, the basic salts or hydroxides precipitate. It is advantageous if the mass produced in this way is subjected to the action of an air stream containing 002.
It is also known to charge carriers of the type used here with basic salts or hydroxides in the specified manner, but it has not yet been recognized that bodies treated in this way have a high binding capacity for hydrogen cyanide.
In the use of such carrier material treated as described above? The invention can only be seen to bind hydrogen cyanide.
In the treatment of the carrier material you go z. B. so before that this with a solution of a copper salt, z. B. CuCl2 and / or CoCl2, soaks. Then the product is placed in a solution of alkali metal hydroxide, e.g. B. NaOH. As a result, metal hydroxide, i.e. Cu (OH) 2 and / or Co (OH) 2, is precipitated in the pores of the carrier. The precipitation product adheres firmly to the carrier. The mass is then dried without the use of heat in a stream of dry air to which a little (up to 5%) CO2 is expediently added. Thereby the hydroxide mixture is increasingly converted into basic carbonate, e.g. B. CuOHCOg and CO2 (OH) 2COa, a process that would also take place in the open air over time.
In this way it is achieved that the preparation in the filter and during ventilation no longer absorbs CO2, that is, it no longer "ages".
