Abstract

Procédé et appareil pour éliminer l'ion cyanure des eaux résiduaires au moyen d'un électrodialyseur, par oxydation anodique. L'eau passe dans le compartiment anodique qui est séparé du compartiment cathodique du dialyseur par une membrane semi-perméable, perméable aux cations ; ce dernier compartiment est parcouru par une solution alcaline. Assainissement des eaux résiduelles par élimination de CN en même temps que des cations présents, sans addition d'aucun réactif.
