Abstract

UN TANINO HIDROLIZABLE INSOLUBLE QUE SE PREPARA A BASE DE DISOLVER POLVO DE TANINO HIDROLIZABLE EN UNA AMONIACO ACUOSO; MEZCLAR LA SOLUCION RESULTANTE CON UNA SOLUCION ACUOSA ALDEHIDA PARA FORMAR UN PRECIPITADO; CALENTAR EL PRECIPITADO; MEZCLAR EL PRECIPITADO CALENTADO CON UN ACIDO MINERAL; Y FILTRAR LA MEZCLA RESULTANTE PARA DEJAR UN RESIDUO EN UN FILTRO. EL TANINO INSOLUBLE DE LA INVENCION PRESENTA UNAS PROPIEDADES DE ADSORCION ELEVADAS PARA ELEMENTOS DE METALES PESADOS Y ES INSOLUBLE TANTO EN AGUA, COMO EN ACIDO O ALCALI. SE PRESENTAN LOS METODOS PARA EL TRATAMIENTO DE LOS LIQUIDOS RESIDUALES Y PARA LA RECUPERACION DE LOS ELEMENTOS DE METALES PESADOS DE LOS MIMOS UTILIZANDO EL TANINO INSOLUBLE DE LA INVENCION.
