Abstract

Procédé d'élimination des composés de cyanurate dissous, tels que l'acide cyanurique et l'ammélide et leurs sels, des liqueurs résiduaires aqueuses. Il consiste à mettre les liqueurs résiduaires en contact avec une solution aqueuse d'hypochlorite de sodium, dans des conditions telles, que la plus grande partie des composés de cyanurate est oxydée en formant de l'azote, de l'anhydride carbonique et du chlorure de sodium. Application à l'épuration des courants résiduaires aqueux.
