Description

Verfahren zur Entfernung kleiner Stoffmengen aus Flüssigkeiten und Gasen.Process for removing small amounts of substance from liquids and Gases.

Es gibt eine Reihe gut adsorbierender Substanzen, welche Gase sowie in Flüssigkeiten gelöste Stoffe an sich zu ziehen und sie so zu entfernen vermögen. Als solche sind Kohle, Bolus, Walkerde und viele andere bekannt. In der Natur des Adsorptionsgleichgewichts liegt es jedoch, daß die Entziehung keine vollkommene ist. There are a number of well adsorbing substances, which gases as well to attract substances dissolved in liquids and thus be able to remove them. As such, charcoal, bolus, fulling earth and many others are known. In the nature of the However, it is in equilibrium of adsorption that the withdrawal is not perfect is.

Versuche haben nun ergeben, daß die Entziehuug eine weit bessere wird, wenn das Adsorbens mit einem Überzug versehen ist, der mit dem zu adsorbierenden Stoff eine Verbindung eingeht. Die zu entziehenden Stoffspuren werden also durch Adsorption am Adsorbens konzentriert und durch Bindung an einem chemischen Agens endgültig festgehalten. So konnten beispielsweise mit einem Bolus, der einen Überzug von Kupferoxyd besaß, letzte Spuren von Schwefelwasserstoff entfernt werden; eine Kohle. die einen Überzug von Quecksilber enthielt, vermochte Spuren von Chlor aus Luft zu entfernen; Ton, der sonst saure Farbstoffe nur schlecht adsorbiert, wurde zu einem guten Adsorbens, wenn man ihm einen dünnen Überzug von Eisenoxyd gab. Experiments have now shown that the withdrawal is far better is when the adsorbent is provided with a coating that is to be adsorbed Substance forms a connection. The traces of fabric to be removed are therefore through Adsorption concentrated on the adsorbent and by binding to a chemical agent finally recorded. For example, with a bolus that has a coating possessed of copper oxide, the last traces of hydrogen sulfide are removed; one Money. which contained a coating of mercury, could produce traces of chlorine Remove air; Clay, which otherwise only poorly adsorbs acidic dyes a good adsorbent if given a thin coating of iron oxide.

An den Versuchsergebnissen ist bemerkenswert, daß die Adsorptionsfähigkeit, der benutzten Stoffe durch den Überzug nicht litt. What is remarkable about the test results is that the adsorption capacity, of the fabrics used did not suffer from the coating.

Bekannt ist es bereits, körnige Massen, wie Sand, Kies oder andere Filtriermaterialien, als Träger mit einem Stoff anderer Zusammensetzung (Manganverbindungen, Zinnoxyd) zu überziehen. Hier dient jedoch der Träger lediglich als Unterlage für einen Stoff, der eine Wirkung entfalten soll; dem Träger kommt keine Konzentrationsarbeit zu. Hierin unterscheidet sich die oben beschriebene neue Erfindung wesentlich von den bekannten Verfahren; bei ihr wird die Beschleunigung der Reaktion durch Erhöhung. der Konzentration des zu entfernenden Stoffs an dem adsorbierenden Träger nutzbar gemacht. It is already known, granular masses such as sand, gravel or others Filter materials, as a carrier with a substance of a different composition (manganese compounds, Tin oxide). Here, however, the carrier only serves as a base for a substance that is supposed to have an effect; there is no work of concentration for the wearer to. This is where the new invention described above differs significantly from the known procedures; in her case the reaction is accelerated by increasing it. the concentration of the substance to be removed on the adsorbent carrier made.

In den Fällen ferner, in denen adsorbierende Pulver, wie Blanc fix oder Schwerspat, z. B. mit gelatinöser Tonerde, oder Bolus mit unlöslichen Metallverbindungen iiberzogen wurden, diente dies keineswegs, wie bei der vorliegenden Erfindung, der Entfernung kleiner Stoffmengen, sondern es wurden damit andere technische Zwecke verfolgt. Also in cases where adsorbent powders such as Blanc fix or barite, e.g. B. with gelatinous clay, or bolus with insoluble metal compounds were overdrawn, this in no way served as in the present invention Removal of small amounts of substance, but other technical purposes tracked.

Der dem vorliegenden Verfahren zugrunde liegende Erfindungsgedanke ist also: Konzentration eines in nur kleiner Menge gasförmig oder gelöst vorhandenen chemischen Stoffs an der Oberfläche eines Adsorbens zu dem Zweck, um ihn durch einen dort befindlichen Überzug mittels chemischer Wechselwirkung zu entfernen. The inventive concept on which the present method is based is therefore: Concentration of something that is only present in a small amount in gaseous or dissolved form chemical substance on the surface of an adsorbent for the purpose of getting it through a to remove the coating located there by means of chemical interaction.

Beispiel I: 50 g Bolus mit einem Überzug von 1 g Kupferoxyd wurden mit 1 1 Wasser, das etwas nach Schwefelwasserstoff roch, einige Minuten geschüttelt. Das Wasser war nach dem Schütteln geruchfrei, während eine Kotrollprobe, die mit der gleichen Menge Bolus ohne Kupferoxydüberzug geschüttelt war, noch deutlich nach Schwefelwasserstoff roch. Example I: 50 g bolus with a coating of 1 g copper oxide was made Shaken for a few minutes with 1 liter of water that smelled a bit of hydrogen sulfide. The water was odorless after shaking, while a control test was carried out with the same amount of bolus without copper oxide coating was shaken clearly Smelled hydrogen sulfide.

Beispiel 2: Durch ein Rohr mit Kohle, die einen Überzug von 2 Gewichtsprozent Quecksilber besaß, wunde Luft geleitet. der etwas Chlor beigemischt wr. Gleichzeitig wurde chlorhaltige Luft auch über gewöhnliche Kohle geleitet. Example 2: Through a pipe with carbon that has a coating of 2 percent by weight Mercury possessed, conducted sore air. which was mixed with some chlorine. Simultaneously air containing chlorine was also passed over ordinary coal.

Während bei der letzteren Probe bald der Chlorgeruch wahrzunehmen und durch Reagentien nachzuweisen war, blieb er bei der Quecksilberkohle aus.While in the latter sample the smell of chlorine was soon to be perceived and could be detected by reagents, it did not occur with the mercury charcoal.

Beispiel 3: Ton, der einen Überzug von 5 Prozent Eisenoxyd erhalten hatte, wurde mit der Lösung von sauren Farbstoffen, z. B. Trypanblau, geschüttelt. Während die Kontrollprobe keine Verminderung in der Färbung zeigte, war bei der mit Eisenoxydton geschüttelten Probe eine starke Entfärbung wahrzunehmen. Example 3: Clay with a coating of 5 percent iron oxide had, was with the solution of acidic dyes, e.g. B. Trypan Blue, shaken. While the control sample showed no reduction in coloration, there was no reduction in coloration If the sample shaken with iron oxide clay, a strong discoloration can be perceived.
