Abstract

UN PROCEDIMIENTO PARA PRODUCIR FOSFATOS METALICOS DIALCALINOS MEDIANTE INTERCAMBIO IONICO, EN DONDE PRIMERAMENTE SE AMONIA UNA FUENTE DE FOSFATO SOLUBLE EN AGUA, TAL COMO ACIDO FOSFORICO O FOSFATO MONOCALCICO, Y DESPUES SE PONE LA SOLUCION DE FOSFATO AMONIADA RESULTANTE EN CONTACTO CON UNA RESINA DE INTERCAMBIO CATIONICO DEBIL, EN LA FORMA DE METAL ALCALINO, PARA PRODUCIR EL FOSFATO METALICO DIALCALINO Y UNA RESINA DE INTERCAMBIO CATIONICO DEBIL CARGADA CON AMONIO, REGENERANDOSE LA RESINA POR CONTACTO CON UNA SOLUCION DE SAL DE METAL ALCALINO QUE INTERCAMBIA METAL ALCALINO POR AMONIO DE TAL MANERA QUE SE PRODUCE UNA RESINA REGENERADA DE INTERCAMBIO CATIONICO DEBIL EN LA FORMA DE METAL ALCALINO Y UNA SAL AMONICA SOLUBLE EN AGUA CORRESPONDIENTE A LA SAL DE METAL ALCALINO INICIAL. EL INVENTO ES APLICABLE PRINCIPALMENTE A LA OBTENCION DE FOSFATOS ALCALINOS UTILIZABLES COMO FERTILIZANTES EN LA AGRICULTURA.
