Title:
両性のイオン交換樹脂を用いて濃厚な塩溶液から過塩素酸塩の除去
Document Type and Number:
Japanese Patent JP5745426
Kind Code:
B2
Abstract:
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.
