Abstract

PROCEDIMIENTO PARA LA PREPARACION DE UN ACIDO INORGANICO PURIFICADO MEDIANTE OXIDACION DE LAS IMPUREZAS INORGANICAS CONTENIDAS EN EL. CONSISTE EN REALIZAR LA OXIDACION CON AYUDA DE PEROXIDO DE HIDROGENO EN PRESENCIA DE UNA CANTIDAD CATALITICA ACTIVA DE UN COMPUESTO DE VANADIO O COMPUESTO DE CROMO SOLUBLE EN AGUA, ESTANDO COMPRENDIDAS LAS CANTIDADES DE ESTOS COMPUESTOS ENTRE 0,1 HASTA 100 PPM (REFERIDAS A LA CANTIDAD DE ACIDO). LOS COMPUESTOS UTILIZADOS SON OXIDO DE VANADIO PENTAVALENTE Y OXIDO DE CROMO PENTAVALENTE, EFECTUANDOSE LA OXIDACION A UNA TEMPERATURA DE 20 HASTA 120GC.
