Abstract

Procédé pour réduire la concentration de perchlorate dans une solution aqueuse concentrée de sels à multiples composantes, faisant intervenir le traitement de la solution saline avec une résine échangeuse d'ions amphotère pour obtenir une résine renfermant du perchlorate adsorbé et de multiples anions ainsi qu'une solution appauvrie en perchlorate; puis le retrait de la solution appauvrie en perchlorate. Les anions sont choisis parmi le chlorure, le chlorate, le perchlorate, le sulfate et le dichromate, qui sont présents dans les procédés électrolytiques de production de chlorate de sodium.
