ABSTRACT:
The invention relates to a process for eliminating adsorbable organic halogen compounds from an aqueous phase, in particular from wastewater or from a process solution, in which the aqueous phase is treated with a nonaqueous extraction medium in a liquid-liquid extraction, which comprises, after the extraction, subjecting the adsorbable organic halogen compounds in the extraction medium to a Wurtz-Fittig reaction. Only small amounts of noncritical products such as NaOH and Hcl, which can be readily removed, are formed in the nonaqueous extraction medium. By means of this process, the cost of the chemicals which conventionally arises in the elimination of the adsorbable organic halogen compounds is considerably decreased.
