Abstract

A method and a device are provided for disposing of an aqueous solution than contains an organic acid and an iron complex and occurs particularly in the decontamination of radioactively contaminated surfaces of components. It is contemplated that the iron complex in the solution is reduced by irradiation with UV light. A dissolved iron salt and carbon dioxide, which is given off, are formed in the process. A
oxidant is then added to the solution that contains the dissolved iron salt and the organic acid. This produces water, and the iron complex foams once again. Some of the dissolved iron salt is removed from the solution by means of a cation exchanger. The solution containing the iron complex is irradiated again with UV light. A cycle process ensues, which continues until all the organic acid is consumed.
