Title:
METHOD FOR EXTRACTING PERCHLORATE-ION FROM AN AQUEOUS SOLUTION
Document Type and Number:
WIPO Patent Application WO2006006892
Kind Code:
A9
Abstract:
The invention relates to the chemical industry and can be used for extracting perchlorate ion form a highly concentrated processing solution having a complex nitrate-chloride-sulphate-iodate composition. The inventive method for extracting perchlorate-ion from an aqueous solution consists in passing said solutuon through a highly basic anionite and, consequently in regenerating said anionite in a metal salt aqueous solution. The anionite is embodied in the form of a nitrate anionite and the regeneration thereof is carried out in an alkali nitrate or alkali-earth metal solution at a temperature of 0-60 °C.
