Abstract

Se refiere a un procedimiento de absorción de óxidos de nitrógeno engases de salida, los cuales se producen a modo de ejemplo en tratamientos de ataquequímico de materiales metálicos con ácido nítrico. Es una solución acuosa, la cual contiene 0,2a 2% en masa de peróxido de hidrógeno y 2 a 20% en masa deácido nítrico, es puesta en contacto con una sustancia y/o disposición activadora de peróxido de hidrógeno.It refers to a process for the absorption of nitrogen oxides in outlet gases, which are produced by way of example in chemical attack treatments of metallic materials with nitric acid. It is an aqueous solution, which contains 0.2 to 2% by mass of hydrogen peroxide and 2 to 20% by mass of nitric acid, is contacted with a hydrogen peroxide activating substance and / or arrangement.
