El carb\u00f3n activo<\/a>\u00a0es un t\u00e9rmino que representa a una gran familia de adsorbentes de base del elemento qu\u00edmico carbono, en forma de carb\u00f3n, que son altamente cristalinos y tienen una gran porosidad interna. Esta gran porosidad interna es lo que le da las grandes aplicaciones al carb\u00f3n activo. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

\nEl carb\u00f3n activo se caracteriza por tener una cantidad muy alta de microporos. Los microporos tienen un tama\u00f1o menor a 2 nan\u00f3metros de radio (1 nan\u00f3metro=1e-9 m). Gracias a esta gran microporosidad su superficie aumenta a cientos de m2, pudiendo tener valores de 2500m2\/g.\n\nLa estructura del carb\u00f3n activo se muestra con una gran cantidad de huecos, recovecos y grietas. En todos estos microporos es donde se produce la adsorci\u00f3n, que es la caracter\u00edstica que le da al carb\u00f3n activo sus aplicaciones.\n\nAl activar un carb\u00f3n lo que estamos haciendo es agrander la superfice y su capacidad de adsorci\u00f3n.  El carb\u00f3n puede ser activado de forma qu\u00edmica o de forma t\u00e9rmica. De forma t\u00e9rmica se consigue una oxidaci\u00f3n por partes del carb\u00f3n, creando los poros, pero evitando que el carb\u00f3n se evapore y se pierda m\u00e1s carb\u00f3n del necesario. El proceso t\u00e9rmico se produce a temperaturas entre 600 y 1000\u00baC.\n<\/p>\n\n\n\n

ADSORCI\u00d3N DEL CARB\u00d3N ACTIVO<\/h2>\n\n\n\n

La principal caracter\u00edstica del carb\u00f3n activado es su adsorci\u00f3n. La adsorci\u00f3n no debe confundirse con la absorci\u00f3n. En la adsorci\u00f3n el s\u00f3lido adsorbente (es este caso el carb\u00f3n activo) se utiliza para eliminar sustancias del agua o del aire. El carb\u00f3n activado tiene una gran superficie interna, gracias a los microporos, de entre 500 y 1500m2\/gramo.<\/p>\n\n\n\n

El carb\u00f3n granulado se usa especialmente en el tratamiento del agua, pudiendo adsorber las siguientes part\u00edculas:<\/p>\n\n\n\n

  • Aceite vegetal<\/li>
  • Sustancias halogenadas: I, Br, Cl, H y F<\/li>
  • Gusto<\/li>
  • Olores<\/li>
  • Levaduras<\/li>
  • Sustancias no solubles en agua<\/li><\/ul>\n\n\n\n

    APLICACIONES DEL CARB\u00d3N ACTIVADO<\/h2>\n\n\n\n
    • Filtros de agua de carb\u00f3n activado. Para potabilizar agua (gracias al carb\u00f3n se pueden retener grasas, aceites, olor, toxinas, insecticidas, compuestos org\u00e1nicos de la descomposici\u00f3n de vegetales o animales \u2026).<\/li>
    • Filtros de aire de carb\u00f3n activado. Eliminaci\u00f3n de olores en el aire. Se utiliza el carb\u00f3n activo por ejemplo en sistemas de recirculaci\u00f3n de aire, o en venteos de drenajes.<\/li>
    • Carb\u00f3n activo en acuarios. Carb\u00f3n activo para eliminaci\u00f3n de sustancias t\u00f3xicas en acuarios.<\/li>
    • Tratar a personas con intoxicaci\u00f3n aguda. Es un ant\u00eddoto universal para adsorci\u00f3n de sustancias t\u00f3xicas tambi\u00e9n dentro de nuestro organismo.<\/li>
    • Decoloraci\u00f3n de aceites vegetales, glucosa de ma\u00edz y otros l\u00edquidos destinados a la alimentaci\u00f3n<\/li>
    • El carb\u00f3n activo se utiliza tambien para decolorar bebidas alcoh\u00f3licas (como el vino).<\/li>
    • Recuperaci\u00f3n de oro<\/li><\/ul>\n\n\n\n

      CARACTER\u00cdSTICAS Y TIPOS DE CARB\u00d3N ACTIVO<\/h2>\n\n\n\n

      Hay diversas formas de clasificar el carb\u00f3n activado, seg\u00fan algunas de sus caracter\u00edsticas, entre las que estar\u00edan: \u00c1rea superficial.<\/strong> El area superficial es la extensi\u00f3n total correspondiente al carb\u00f3n activo teniendo en cuenta todos los microporos. Es el principal indicador de la actividad del carb\u00f3n activado. <\/span>Radios porales. <\/span><\/strong>El tama\u00f1o de los radios de los poros es otra de las maneras de conocer el funcionamiento del material. * <\/span>Microporos radio menor 2 nm  * Mesoporos r \u2248 2-50 nm  *Macroporos r mayor 50 nm N\u00famero de yodo.<\/strong> Se utiliza habitualmente para caracterizar la adsorci\u00f3n del carb\u00f3n, a trav\u00e9s de la capacidad de adsorci\u00f3n de yodo en la soluci\u00f3n. <\/span>Dureza. <\/span><\/strong>La dureza es un factormuy importante ya que va a dar la vida \u00fatil de los filtros y la forma en que van a ser manipulados. Puede haber muchas variaciones de dureza. Tama\u00f1o de las part\u00edculas. <\/span><\/strong>Cuanto m\u00e1s finas son las part\u00edculas mejor es el acceso al \u00e1rea de la superficie y m\u00e1s r\u00e1pido se produce la adsorci\u00f3n. <\/span><\/p>\n\n\n\n
