Abstract

L’invention concerne un procédé de traitement d’un effluent liquide contenant des ions chlorures. Le procédé comprend l’ajout d’oxyde d’argent à l’effluent pour produire un précipité de chlorure d’argent, lequel peut être recyclé en oxyde d’argent par réaction avec une solution d’hydroxyde alcalin.
