Abstract

METODO PARA LA ELIMINACION DE CROMO DE EFLUENTES LIQUIDOS Y SU RECUPERACION. COMPRENDE TRATAR EL EFLUENTE CON UN AGENTE EXTRACTANTE, PRIMENE 81R, EN UNA DISOLUCION ORGANICA (DISOLVENTE, QUEROSENO O PETROLEO). LA DISOLUCION ACUOSA QUEDA LIBRE DE CROMO Y ES POSIBLE SU VERTIDO TRAS LA CORRECCION DEL PH, SI FUERE NECESARIO. EL CROMO SE REEXTRAE DE LA FASE ORGANICA MEDIANTE UNA DISOLUCION ALCALINA, PRODUCIENDOSE UNA FASE ORGANICA REGENERADA Y UNA SUSPENSION ACUOSA DE HIDROXIDO DE CROMO (III). LA FASE ORGANICA REGENERADA SE RECIRCULA A CABEZA DE PROCESO. DE LA SUSPENSION ACUOSA SE OBTIENEN POR FILTRACION UN LODO DE HIDROXIDO DE CROMO (III). APLICACION MEDIOAMBIENTAL EN EL AMBITO DE LA DEPURACION DE EFLUENTES INDUSTRIALES CONTAMINADOS CON CROMO.
