Abstract
UN METODO PARA SEPARAR N SUB 2 O SUB 5 DE SU DISOLUCION EN ACIDO NITRICO QUE CONSISTE EN LOS PASOS SIGUIENTES: (A) PREPARAR, MEDIANTE LA OXIDACION ELECTROQUIMICA DE N SUB 2 O SUB 4 EN ACIDO NITRICO, UNA DISOLUCION DE ACIDO NITRICO A UNA TEMPERATURA DE POR LO MENOS 10 C QUE CONTENGA POR LO MENOS UN 45% POR PESO DE (N SUB 2 O SUB 4 + N SUB 2 O SUB 5 ) DISUELTO Y QUE TENGA UN N SUB 2 O SUB 5 DISUELTO: RELACION DE ACIDO NITRICO POR PESO DE POR LO MENOS 1:3; Y (B) ENFRIAR LA DISOLUCION ACIDA A MENOS DE 8 C HASTA QUE UN SOLVATO DE N SUB 2 O SUB 5 SE PRECIPITA DE LA DISOLUCION. LA VENTAJA PRINCIPAL DE LA INVENCION ES QUE PERMITE UTILIZAR METODOS ELECTROQUIMICOS ELECTRICAMENTE EFICACES EN LA PRODUCCION DE LA DISOLUCION ACIDA DE LA QUE SE RECUPERA EL SOLUTO.
