Halogenated hydrocarbons reductive dehalogenation

Certain halogenated hydrocarbons such as halo-thane, undergo reductive dehalogenation. 

The partially halogenated hydrocarbons, such as poly(vinylidene fluoride) (PVDF) and polyvinylchloride (PVC) are not carbonizable by direct reductive dehalogenation [59]. Nevertheless, PVDF carbonizes indirectly by... 

Reductive dehalogenation is a mechanism for the anaerobic biotransformation of chlorinated hydrocarbons such as hexachlorobenzene (HCB). In reductive dehalogenation, the halogenated compound serves as the electron acceptor rather than the donor that requires a separate carbon source. In a microbially catalyzed reaction, a halide ion is replaced by a hydrogen ion (Figure 13.7). The removal of halide ions results in compounds that are generally easier to degrade, and, in some instances, are completely mineralized.
