Abstract

PROCEDIMIENTO PARA LA ELIMINACION DE MOLIBDENO DE DISOLUCIONES ACUOSAS DE SALES DE MANGANESO (II), MEDIANTE ADSORCION SOBRE DIOXIDO DE MANGANESO Y SEPARACION DEL PRECIPITADO. CONSISTE EN TRATAR LA DISOLUCION QUE CONTIENE MANGANESO (II), A UN PH ENTRE 1,5 Y 2,5, CON UN AGENTE OXIDANTE, TAL COMO PERMANGANATO POTASICO O HIPOCLORITO SODICO, A UNA TEMPERATURA COMPRENDIDA ENTRE 50 C Y 80 C PARA FORMAR UNA PEQUEÑA CANTIDAD DE DIOXIDO DE MANGANESO, QUE ADSORBE LA IMPUREZA DE MOLIBDENO; SEGUIDO DE SEPARACION DEL PRECIPITADO, TRAS UN TIEMPO DE CONTACTO NO INFERIOR A 15 MINUTOS. ESTAS DISOLUCIONES SE EMPLEAN PARA LA OBTENCION ELECTROLITICA DE MANGANESO.
