Abstract
SE PRESENTA UN PROCESO PARA EL TRATAMIENTO DE AGUA PARA EXTRAER LOS CONTAMINANTES DE IONES METALICOS QUE HAY EN ELLA, SIENDO DICHOS CONTAMINANTES DE IONES METALICOS SELECCIONADOS DEL GRUPO QUE CONSISTE EN METALES DE LOS GRUPOS 8, 1B, 2B, 4A, 5A O 6A DE LA TABLA PERIODICA, METALES LANTANIDOS Y METALES DE LOS ACTINIDOS QUE INCLUYEN METALES DE ELEMENTOS TRANSURANICOS, QUE CONSISTE EN AJUSTAR EL PH DE UNA FUENTE DE AGUA QUE CONTIENE CONTAMINANTES DE IONES METALICOS A UN VALOR DE 6,5 A 14,0 APROXIMADAMENTE, MEZCLAR LA FUENTE DE AGUA CON UNA MEZCLA DE UN FERRATO ALCALINO-TERREO O ALCALINO Y UNA SAL DISOLUBLE EN AGUA, EJ., SAL DE ZIRCONIO, EN UNA CANTIDAD SUFICIENTE COMO PARA FORMAR UN PRECIPITADO DENTRO DE LA FUENTE DE AGUA, PERMITIR QUE EL PRECIPITADO QUE HAY EN LA MEZCLA SE SEPARE Y ASI OBTENER UN LIQUIDO SUPERNATANTE QUE TENGA UNA CONCENTRACION DE CONTAMINANTES DE IONES METALICOS Y SEPARAR EL LIQUIDO SUPERNATANTE QUE TIENE LA CONCENTRACION DE CONTAMINANTES DE IONES METALICOS. TAMBIEN SE PRESENTA UNA COMPOSICION DE MATERIA QUE INCLUYE UN FERRATO ALCANINO-TERREO O ALCALINO Y UNA SAL DISOLUBLE EN AGUA, EJ., UNA SAL DE ZIRCONIO.
