Abstract
SE EVAPORA AL VACIO EN UN EVAPORADOR (7) Y SE CONDENSA UNA PARTE SUSTANCIAL DEL AGUA CONTENIDA EN LA SOLUCION USADA, PARA OBTENER AGUA LIGERAMENTE ACIDA Y UNA SOLUCION ACIDA CONCENTRADA CONTAMINADA POR FLUORURO DE CIRCONIO ZRF{SUB,4}. SE TRATA POR EVAPORACION AL VACIO EN UN CRISTALIZADOR (8) LA SOLUCION ACIDA CONCENTRADA CONTAMINADA, PARA OBTENER CRISTALES DE FLUORURO DE CIRCONIO ZRF{SUB,4} Y UNA SOLUCION ACIDA CONCENTRADA DEPURADA. SE MEZCLA EL AGUA LIGERAMENTE ACIDA Y LA SOLUCION ACIDA CONCENTRADA DEPURADA EN PROPORCIONES DESEADAS PARA OBTENER UNA SOLUCION DE DECAPADO REGENERADA.
