Abstract
Procedimiento para la descontaminación regulable automáticamente, de aguas residuales que contienen iones nitrito, en el que los iones nitrito son oxidados para formar iones nitrato mediante peróxido de hidrógeno en el margen de pH débilmente ácido, caracterizado porque durante el curso de la reacción de oxidación se añade continuamente o en porciones peróxido de hidrógeno, con medición constante del pH, y la adición se interrumpe cuando ya no produce ninguna disminución adicional del valor del pH.
