Abstract
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.
Claims10
A method of purifying an aqueous solution (14) comprising iodide, calcium and/or magnesium ions, according to which in a first step the solution is alkalized in order to precipitate calcium and/or magnesium, which are separated out, in a second step the aqueous solution (19) from the first step is oxidized in order to oxidize the iodide ions to iodine and in a third step the iodine is removed by bringing the oxidized solution (8) into contact with a basic halogenated anion exchange resin (5), the exchange resin being regenerated by using a portion (13) of the aqueous solution from the first step.
