Patent DE-4410747-A1 (DE)
Inventor: BERTHOLDT HORST-OTTO
IPC: G21F9/06
Filed: 1994-03-28
Abstract: The invention concerns a method and device for disposing of a solution containing an organic acid and an iron complex, particularly the type of solution arising from the decontamination of the surfaces of radioactively contaminated equipment. The invention calls for the iron complex in the solution to be reduced by irradiation with UV light, thus forming a dissolved iron salt and carbon dioxide which is given off. An oxidizing agent is then added to the solution containing the dissolved iron salt and the organic acid. Water is formed and the iron complex is produced again. Part of the dissolved iron salt is removed from the solution in a cationic ion-exchanger. The solution containing the iron complex is again irradiated with UV light and the process repeated until all the organic acid has been consumed.
