Abstract
UN METODO PARA ELIMINAR METALES PESADOS, ESPECIALMENTE CADMIO, A PARTIR DE SOLUCIONES QUE CONTIENEN ACIDO FOSFORICO, PRINCIPALMENTE LAS SOLUCIONES PREPARADAS POR DIGESTION DE FOSFATO MINERAL CON ACIDO NITRICO Y SUBSIGUIENTE ELIMINACION DE LA PARTE PRINCIPAL DEL CALCIO A PARTIR DE LAS AGUAS MADRES. LA SOLUCION DE ACIDO FOSFORICO ES PURIFICADA PREVIAMENTE PARA LA ELIMINACION DEL LODO Y LOS MATERIALES INSOLUBLES Y LUEGO ES PARCIALMENTE NEUTRALIZADA CON AMONIACO A PH 1,4-2 Y ENFRIADA A 5-40GC. SE AÑADEN SALES METALICAS DE O-ESTERES ACIDO DITIO-CARBONICO PARA PRECIPITAR LOS METALES PESADOS, QUE LUEGO SON SEPARADOS A PARTIR DE LA SOLUCION. LA SOLUCION ES PREFERIBLEMENTE NEUTRALIZADA A PH 1,6-1,8 Y ENFRIADA A 10-20GC ANTES DE PRECIPITACION DE LOS METALES PESADOS, QUE LUEGO PUEDEN SER ELIMINADOS A PARTIR DE LA SOLUCION DE ACIDO FOSFORICO MEDIANTE FLOTACION Y SUBSIGUIENTE FILTRACION.
