Abstract

Una forma de realización de un método para recuperar el ácido nítrico de una solución de decapado con ácido que incluye introducir un material tratante que comprende por lo menos un producto químico en una solución de decapado que comprende ácido nítrico libre. El material tratante reacciona con por lo menos una parte del ácido nítrico libre de la solución de decapado y produce NOX. Se pone en contacto con ozono a una corriente de gas que comprende por lo menos una parte de los NOX, para formar de esa manera productos de oxidación que incluyen sesquióxido de nitrógeno y pentóxido de nitrógeno. Por lo menos una parte del sesquióxido de nitrógeno y el pentóxido de nitrógeno se pone en contacto con agua, para formar de esa manera ácido nítrico, y se recolecta por lo menos una parte del ácido nítrico.
