Abstract
PROCEDIMIENTO PARA LA ELIMINACION DE HUMATOS Y OTRAS IMPUREZAS DEL ACIDO FOSFORICO. CONSISTE EN MEZCLAR EL ACIDO FOSFORICO CON UN AGENTE ESPESANTE (TAL COMO BENTONITA), PARA LA FORMACION DE LAS IMPUREZAS SUSPENDIDAS, AÑADIENDO UN AGENTE FLOCUANTE EN CANTIDAD SUFICIENTE PARA SEDIMENTAR LOS FLOCULOS. A CONTINUACION SE SEPARAN LOS LODOS DEPOSITADOS DE LA SOLUCION DE ACIDO Y, POR ULTIMO SE PONEN EN CONTACTO ESTA SOLUCION CON CARBONO ACTIVADO, AL OBJETO DE ELIMINAR LAS IMPUREZAS RESTANTES.
