Abstract
Procedure for the purification of waste water, particularly radioactively contaminated water, characterized in that the sorbent that retains the cations is regenerated by means of a solution (for example iron chloride, lead nitrate, barium chloride and the like), whose cationic component forms with anions, optionally with anionic impurities that are contained in the purified water (for example with sulfate, carbonate, bicarbonate, hydroxyl anions and the like), a precipitate that is capable of dragging with it cationic impurities, for example Ra226, and at at the same time remain adhered on the surface and inside the pores of the sorbent.
