ABSTRACT:
A method for removing 99% of the sodium ions from a natural or industrial brine containing dissolved salts of metals of Group 1A of the periodic chart and in which brine sodium ions are not the predominant metal ions by contacting the brine at pH 11 to 12 with an ion exchanger selected from crystalline antimonic acid and polyantimonic acid, and removing from contact with the ion exchanger the brine with greater than 99% of the sodium ions removed.
