<p>The invention concerns a process for the treatment of a solution used for decontamination of a radioactively contamined surface, the solution containing radioactive metal ions and an organic complexing agent. The process comprises treating the solution with a reagent suitable for the destruction of the complexing agent and containing a metal capable of existing in more than one oxidation state. The pH of the resultant solution is then raised to a level at which the metal of the reagent precipitates or flocs out of the solution. The reagent may be, for instance, Fenton's reagent and the solution may be additionally treated with electromagnetic radiation.</p> |
