Abstract

Un método para el tratamiento de aguas de desecho que comprende un compuesto de cianuro y un compuesto metálico, en donde dichas aguas de desecho son sometidas a un sólo paso de oxidación durante el cual los compuestos de cianuros son convertidos en dióxido de carbono y nitrógeno, este paso de oxidación que comprende el mezclado de las aguas de desecho con una solución de cloro y un agente alcalino para obtener una mezcla, el agente alcalino que se agrega en tal cantidad para mantener el pH de dicha mezcla entre 8.8 y 9.5 y la solución de cloro que se agrega en tal cantidad para mantener el potencial de óxido-reducción de la mezcla entre 150 y 450 mV.
