PERCHLORATE REMOVAL FROM CONCENTRATED SALT SOLUTIONS USING AMPHOTERIC ION-EXCHANGE RESINS
A process for reducing the concentration of perchlorate in an aqueous concentrated multi-component salt solution comprising treating the salt solution with an amphoteric ion-exchange resin to provide an adsorbed perchlorate and multi anion- containing resin and a perchlorate depleted solution; and r...

| description | A process for reducing the concentration of perchlorate in an aqueous concentrated multi-component salt solution comprising treating the salt solution with an amphoteric ion-exchange resin to provide an adsorbed perchlorate and multi anion- containing resin and a perchlorate depleted solution; and removing the perchlorate depleted solution. The multi--anion are selected from chloride, chlorate, perchlorate, sulphate, and dichromate, present in electrolytic processes for the production of sodium chlorate.
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. |
