A method for the disposal of dissolved organic complexing agent is selected from an aqueous solution, for example, radioactive waste waters

摘要

The invention relates to a process and an installation for the destruction of organic solutes, in particular of complexing agents present in an aqueous solution such as a radioactive effluent. & br / according to this process, the aqueous solution is subjected to an electrolysis in a cell (1) comprising a working electrode (51, 52...) by applying to this electrode a sufficient potential to destroy the solutes by electrolytic oxidation and it changes periodically the applied potential or the direction of passage of the current flowing through the cell so as to provide a regeneration of the working electrode. & br / the solutes can be organic acids such as formic acid, dihydroxymalonic acids, or oxalic acid.
