Abstract

UN METODO PARA ADSORBER Y SEPARAR UN ELEMENTO METALICO PESADO UTILIZANDO UN ADSORBENTE DE TANINO QUE COMPRENDE: (A) AJUSTE DEL PH A UNA SOLUCION QUE CONTIENE UNA PLURALIDAD DE ELEMENTOS METALICOS PESADOS A UN PH PREDETERMINADO; (B) CONTACTO DEL ADSORBENTE CON LA SOLUCION EN LA QUE ESTA AJUSTADO EL PH DEL MISMO; (C) AJUSTE DEL PH DE LA SOLUCION PUESTA EN CONTACTO CON EL ADSORBENTE A UN PH DIFERENTE DEL PH PREDETERMINADO; Y (D) CONTACTO DE LA SOLUCION EN LA QUE ESTA AJUSTADO EL PH DE LA MISMA EN EL PASO (D) CON EL ADSORBENTE PREPARADO EN EL PASO (A). DE ACUERDO CON EL METODO DE LA INVENCION, TODOS LOS ELEMENTOS METALICOS PESADOS PUEDEN SER SEPARADOS Y ADSORBIDOS EFICAZMENTE UTILIZANDO UN ADSORBENTE DE TANINO A PARTIR DE UNA SOLUCION QUE CONTIENE UN NUMERO DE ELEMENTOS METALICOS PESADOS. TAMBIEN SE DESCRIBE UN METODO DE REGENERACION DE UN ADSORBENTE TANINO.
