Title (EN) DEHALOGENATION OF HALOGENATED COMPOUNDS
(FR) DESHALOGENATION DE COMPOSES HALOGENE
Abstract: front page image
(EN)Chemical process for degrading halogenated organic compound having at least one C-halogen group and preferably a plurality of such groups to remove halogen atoms from said compound by treating it with ultra-violet (UV) radiation (2) and hydrogen (6) preferably, though not necessarily in alkaline liquid solution. Process for degrading such compound which is capable of forming alkali metal salts by treating it in aqueous alkaline solution with UV radiation (2). The process can be used generally as a means for dehalogenation and is particularly useful in the treatment of contaminated effluent wastes from manufacturing processes or from contaminated water, soil, sludges or other wastes already present in the environment. An example of a compound effectively treated by the processes of the invention is kepone, decachloropentacyclo (5.3.0.02,6.03,9.04,8) decan-5-one.
(FR)Procede chimique de degradation d"un compose organique halogene ayant au moins un groupe C-halogene et de preference une pluralite de tels groupes pour enlever les atomes d"halogenes dudit compose en le traitant avec des rayons (2) ultraviolets (UV) et de l"hydrogene (6), de preference dans une solution liquide alcaline bien que ce ne soit pas necessaire. procede de degradation d"un tel compose qui est capable de former des sels metalliques alcalins en le traitant dans une solution aqueuse alcaline avec des rayons (2) ultraviolets. Le procede peut etre utilise d"une facon generale pour la deshalogenation et il est particulierement utile pour le traitement des dechets des eaux residuaires industrielles polluees ou d"eaux, sols, boues contamines ou d"autres dechets deja presents dans l"environnement. Un exemple d"un compose traite efficacement par le procede de l"invention est le kepone, decachloropentacyclo (5.3.0.02, 6. 9.04, 8) decan-5-one.
