Abstract

SE DESCUBRE UN PROCESO PARA LA DETOXIFICACION DE LOS EFLUENTES QUE CONTIENEN CIANURO, MEDIANTE EL TRATAMIENTO DE DICHAS AGUAS RESIDUALES CON UNA MEZCLA DE PEROXIDO DE HIDROGENO Y ACIDO FOSFORICO. EL RATIO MOLAR DEL ACIDO FOSFORICO CON RESPECTO AL HIDROGENO EN LA MEZCLA ES DE 1:100 Y DE 1:3. EL CONSUMO DE PEROXIDO DE HIDROGENO PODRIA DISMINUIRSE EMPLEANDO DICHA MEZCLA EN LUGAR DEL PEROXIDO DE HIDROGENO SOLO.
