REMOVING PERCHLORATE FROM CONCENTRATED SALT SOLUTIONS USING AMPHOTERIC ION-EXCHANGE RESINS Russian patent published in 2013 - IPC C02F1/42 C02F1/58 B01J43/00 

Abstract RU 2482071 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of reducing concentration of perchlorate in an aqueous concentrated multi-component sodium chlorate solution primarily containing sodium chlorate. The method involves treating said sodium chlorate solution with an amphoteric resin to form adsorbed perchlorate on the resin which contains multiple anions and a perchlorate depleted solution; and removing said perchlorate depleted solution.

EFFECT: selective method of separating perchlorate from concentrated solutions while ensuring cheap removal thereof without using chemical agents.
