Process for electrochemical decomposition of nitric acid

Creators

Description

Nitric acid is to be decomposed by an electrochemical process producing mostly or exclusively nitrous oxide. In particular, nitric acid is to be removed from medium-level or high-level solutions of nuclear waste from reprocessing plants. The process is characterized so that the reaction is carried out in the presence of silver or silver ions. (orig.)

Abstract (German)

Die Erfindung betrifft ein Verfahren zur elektrochemischen Zersetzung von Salpetersaeure unter weitgehender oder ausschliesslicher Bildung von Distickstoffmonoxid. Insbesondere betrifft die Erfindung ein Verfahren zum Entfernen von Salpetersaeure aus mittel- oder hochaktiven Abfalloesungen der Kernbrennstoffwiederaufarbeitung. Das Verfahren ist dadurch gekennzeichnet, dass die elektrochemische Zersetzungsreaktion der Salpetersaeure in Gegenwart von Silber oder Silberionen durchgefuehrt wird. (orig.)
