For instance, the reductive dechlorination of CFCs is complete and produces several hydrofluorocarbons (HFC) plus chloride. Hydrodechlorination (HDC) is a type of reductive dechlorination that is useful due to its high reaction rate. It uses H 2 as the reducing agent over a range of potential electrode reactors and catalysts. [20]
The rates of dechlorination are enhanced by the surfactant Triton X-114. [15] Further reading ... (ed.), Chemical Degradation Methods for Wastes and Pollutants ...
Reductive dechlorination is rarely useful in chemical synthesis, but is a key step in the biodegradation of several organochlorine persistent pollutants. [ citation needed ] Applications
Microbial dechlorination tends to be rather slow-acting in comparison to other methods. Enzymes extracted from microbes can show PCB activity. In 2005, Shewanella oneidensis biodegraded a high percentage of PCBs in soil samples. [188] A low voltage current can stimulate the microbial degradation of PCBs. [189]
Lithium-halogen exchange is essentially irrelevant to remediation, but the method is useful for fine chemical synthesis. [4] [5] [6] Sodium metal has been used for dehalogenation process. [7] [8] Removal of halogen atom from arene-halides in the presence of Grignard agent and water for the formation of new compound is known as Grignard ...
787 program managers and employees implicitly understood this new production method, and we cautiously believed it might work. But it began to unravel bit by bit and ended in a three-year delay.
A commonly used strategy for the removal of TCE and PCE from groundwater is the use of bioremediation via enhanced reductive dechlorination (ERD). [14] ERD involves in-situ injections of dehalorespiring bacteria, among fermentable organic substrates serving as electron donors , while the two pollutants, TCE and PCE, act as the electron ...
The Heimlich maneuver is a first-aid method recommended by most health organizations, which uses abdominal thrusts to dislodge an obstruction from a person’s windpipe. Boy, 8, Saves Choking ...
