A process and filter for producing NO2-free nitrogen monoxide are based on putting a NO2-containing gas or liquid in contact with a material that contains a sulphurous polymer, for example polyarylene thioether, in particular polyphenylene sulphide. The process or filter are suitable for generating NO2-free nitrogen monoxide-nitrogen-air mixtures for medical applications.
Un procédé et un filtre de production de monoxyde d'azote exempt de NO¿2? se fondent sur la mise en contact d'un gaz ou d'un liquide contenant du NO¿2? avec un matériau qui contient un polymère sulfureux. Parmi les polymères sulfureux on compte par exemple le thioéther de polyarylène, notamment le sulfure de polyphénylène. Ce procédé ou ce filtre sont utiles pour générer des mélanges d'air, d'azote et de monoxyde d'azote exempts de NO¿2? pour des applications médicales.
