Abstract
The present invention relates to a process for decontaminating aqueous media comprising organic contaminants. The process is targeted at reducing the COD and/or the TOC of an aqueous medium comprising organic molecules. It consists in subjecting the aqueous medium to an electron beam generated by an electron accelerator in the presence of a catalyst and in then removing the precipitates formed from the treated solution, said catalyst comprising a metal ion persulfate and optionally an Fe(II) salt or an Fe(III) salt.
Claims10
A process for reducing the COD (chemical oxygen demand) and/or the TOC (total organic carbon) of an aqueous medium comprising organic molecules, comprising subjecting said aqueous medium to an electron beam generated by an electron accelerator in the presence of a catalyst and removing the precipitates formed from the treated solution, said catalyst comprising a metal ion persulfate.
