Selective mechanochemical dehalogenation of chlorobenzenes over calcium hydride

Article Abstract:

The use of mechanochemical processes in destroying organochlorides is one of the potential alternatives to the current oxidative methods used in the remediation of toxic chlorinated organic chlorides. A current research examined the dehalogenation of organic compounds, the hexachlorobenzene and the chlorobenzene, through a ball milling process at low temperature and pressure using calcium hydride as the reactive substrate. Results show that the process, which produced only benzene and chloride salts, avoided the problem encountered in oxidative remediation methods where toxic cogeners and unwanted by-products were produced.

Corrinoid-mediated reduction of tetrachloroethene, trichloroethene, and trichlorofluoroethene in homogeneous aqueous solution: reaction kinetics and reaction mechanisms

Article Abstract:

Research shows that halogenated ethenes, including perchloroethene (PCE) and trichloroethene (TCE), may be reduced microbially into dichloroethenes. Such reductive reactions provide ways for treating halogenated solvent wastes and potential remediation processes for removing the chemicals from contaminated soils and aquifers. The research involved investigations on the reduction-oxidation potential and pH's effect on cobalamin-mediated reduction of PCE, TCE and trichlorofluoroethene in homogeneous aqueous solution.

pH-dependent sorption of chlorinated guaiacols on estuarine sediments: the effects of humic acids and TOC

Article Abstract:

Chlorinated guaiacols are organochlorines found in effluents from chlorine-based bleached kraft pulp and paper mill processes that are resistant to traditional wastewater degradation methods and are capable of bioconcentration and biomagnification. Research shows that the total acid content, including humic acid, of a sediment is an influential factor in controlling the sorption of chlorinated guaiacols.
