<p>Method of purifying an aqueous solution comprising iodide, calcium and magnesium ions, according to which in a first step the solution is alkalized in order to precipitate calcium and magnesium, which are separated out, and in a second step the aqueous solution from the separation is oxidized in order to oxidize the iodide ions to iodine that is removed over a basic halogenated anion exchange resin, the exchange resin being regenerated by using a portion of the aqueous solution from the separation.</p> |
