Abstract

PROCEDIMIENTO PARA PRODUCIR UNA SOLUCION ACUOSA DE SULFATO FERRICO QUE TIENDE A SER INESTABLE CUANDO SE SOMETE A BAJAS TEMPERATURAS. SE OBTIENEN AHORA SOLUCIONES MAS ESTABLES OXIDANDO SULFATO FERROSO CON ACIDO NITRICO Y ACIDO SULFURICO SEGUIDO DEL TRATAMIENTO CON UN PEROXIDO. LOS PRODUCTOS ESTAN EXENTOS DE IONES FERROSOS Y PUEDEN TENER UN INTERVALO DEL CONTENIDO DE ACIDO LIBRE AL TIEMPO QUE PERMANECEN ESTABLES. PARTICULARMENTE UTIL COMO PEROXIDO ES PEROXIDO DE HIDROGENO.
