Abstract

Synthetic active carbon is prepd. by introducing a fine pored form of the carbon into the coarse pores of an inert matrix material. The matrix is e.g. of a mixt. of clay, gypsum, porous silicates, fuller's earth, natural or synthetic zeolites with montmorrilonites in a ratio of 10-70%. Pref. the mixt. is formed into spheres or granules and activated by heating to 700 deg.C under an inert atmos. USE/ADVANTAGE - Prods. have better abrasion resistance than conventional active carbon. Esp. useful for purificn. of drinking water e.g. to remove contaminants e.g. toxic concns. of Pb, Cd and Hg and other adsorbable materials e.g. pesticides and dyes and inorganic materials e.g. heavy metals and radioactive elements.

Description

Die Verwendung von feinporigen Erscheinungsformen der Kohlenstoffe innerhalb der groben Poren einer inerten Matrix wurde schon in der Patentanmeldung P 39 19 567.8 beschrieben. Es wurde jetzt festgestellt, daß die grobporige inerte Matrix aus Mischungen von Bleicherde, Zeolithen (natürlicher oder synthetischer Art), mit Ton, Gips, porösen Silikaten oder grobporiger Holzkohle, Steinkohle, porösen Kunststoffen jeder Art, oder jeder Sorte Ruß, bestehen kann. Erhebliche Verbesserungen der Adsorptionskraft solcher künstlicher aktiver Kohle wurde festgestellt. Im Falle von Mischungen von Zeolithen z. B. sind zusätzliche Ionenaustauscheigenschaften anwesend. Der Erfindung liegt daher die Aufgabe zugrunde, die Entfernung nicht nur von adsorbierbaren Stoffen aus Wasser, sondern auch die Adsorption von anorganischen Giften, wie z. B. Schwermetalle oder radioaktive Elemente.The use of fine-pored forms of carbon within the Coarse pores of an inert matrix have already been described in patent application P 39 19 567.8 described. It has now been found that the coarse pore inert matrix is made up of mixtures of bleaching earth, zeolites (natural or synthetic), with clay, plaster, porous Silicates or coarse-pored charcoal, hard coal, porous plastics of any kind, or any kind of soot can exist. Significant improvements in the adsorption power of such Artificial active coal has been found. In the case of mixtures of zeolites z. B. additional ion exchange properties are present. The invention is therefore the Task, the removal not only of adsorbable substances from water, but also the adsorption of inorganic poisons, such as. B. heavy metals or radioactive elements.

Nachfolgend ein Beispiel eines LaboransatzesBelow is an example of a laboratory approach

Durchfeuchteter Ton (50 g) wurde mit 3 g Ruß und 10 g synthetischem Zeolith, wie z. B. "Wessalith P", der Firma Degussa, vermischt. Aus dieser Masse wurden Kügelchen oder Granulat geformt. Nach Verbrennung bei 700° Celsius in Stickstoff-Atmosphäre erhält man das gewünschte Material, welches abriebfest, und daher besser geeignet, als gewöhnliche Aktivkohle ist. Das Material entfernt z. B. giftige Konzentrationen von Blei, Cadmium und Quecksilber aus Trinkwasser. Ferner wurde eine Senkung des Härtegrades des Wassers beobachtet. Pestizide und andere adsorbierbare Stoffe, sowie Farbstoffe, wurden auch grundsätzlich entfernt.Moistened clay (50 g) was treated with 3 g of carbon black and 10 g of synthetic zeolite, such as. B. "Wessalith P" from Degussa. From this mass, beads or Shaped granules. After combustion at 700 ° Celsius in a nitrogen atmosphere, one obtains the desired material, which is abrasion-resistant and therefore more suitable than ordinary Activated carbon is. The material removes e.g. B. toxic concentrations of lead, cadmium and Mercury from drinking water. There was also a decrease in the hardness of the water observed. Pesticides and other adsorbable substances, as well as dyes, have also been basically removed.
