Abstract

La presente invención pertenece al campo de la Ciencia Ambiental. El objetivo de la presente invención es la inmovilización de taninos vegetales en la corteza de los árboles forestales para que pueda ser usada para la remoción de metales pesados de aguas. La invención está basada en un método químico para inmovilizar tatinos vegetales en la corteza de árboles y comprenda el procesamiento de la corteza desde su secado previo, trituración, el proceso de inmovilización de los taninos por vía química y su utilización para remover metales pesados presentes en aguas naturales o residuales. Es aplicable para la remoción de metales pesados en el tratamiento de aguas residuales que los contienen en concentraciones bajas.The present invention belongs to the field of Environmental Science. The objective of the present invention is the immobilization of vegetable tannins in the bark of forest trees so that it can be used for the removal of heavy metals from waters. The invention is based on a chemical method to immobilize plant tatinos in the bark of trees and includes the processing of the bark from its previous drying, crushing, the process of immobilization of tannins by chemical means and its use to remove heavy metals present in natural or wastewater It is applicable for the removal of heavy metals in the treatment of wastewater containing them in low concentrations.
