Abstract
Processes for the treatment of solutions used for the decontamination of radioactively contaminated surfaces wherein the solution contains radioactive metal ions and organic complexing agents are described herein. The processes include treating the solutions with a reagent suitable for the destruction of the complexing agent and contains a metal capable of existing in more than one oxidation state, and raising the pH of the resultant solution to a level at which the metal of the reagent precipitates or flocs out of the solution. Processes in which the contaminated solutions are treated with electromagnetic radiation, treated with UV or visible radiation, and treated at an ambient temperature are also described herein.
