Abstract

PROCEDIMIENTO EN LA PERPARACION E PIGMENTOS AZUL HIERRO. CONSISTE EN LA PERCIPITACION DE UNA PASTA BLANCA MEDIANTE IONS DE METALES ALCALINOS, CIANUROS O IONES FERROCIANURO COMPLEJOS, A IONES HIERRO, EN DOS FASES, AÑADIENDOSE EN LA PRIMERA FASE, COMO METALES ALCALINOS, IONES POTASIO, Y EN LA SEGUNDA IONES SODIO. LA SUSPENSION OBTENIDA SE DILUYE CON AGUA SE SEPARA POR DECANTACION LA SOLUCION QUE SOBRENADA, SE AÑADEN SALES DE POTASIO, SE CALIENTA Y A CONTINUACION SE ENFRIA, AÑADIENDOSE UN ACIDO INORGANICO EN FORMA DE UNA SOLUCION ACUOSA Y UN AGENTE OXIDANTE. DESPUES DE LA OXIDACION SE SEPARA EL PIGMENTO DE AZUL DE HIERRO RESPECTO A LA SOLUCION Y SE TRATA SEGUN PROCEDIMIENTOS CONOCIDOS.
