We investigate a synthetic iron porphyrin, (TPP)FeCl (Figure 1) (where TPP = the dianion of tetraphenylporphyrin), for its catalytic properties toward DDT dechlorination
in pyridine and DMSO.
Therefore, it was the aim of present study to develop a cost-effective and efficient technique for dechlorination
of OCPs for developing countries so that we can help protect our environment and human health.
However, if we treat UV photon as a kind of particle but not electromagnetic wave, the dechlorination
reaction now has two reactants: PCB molecule and photon.
The presence of water supports/accelerates many of the above reactions by hydrolyzing the POE esters to produce carboxylic acids, by increasing the solubility of the copper carboxylates, by promoting the corrosion of the steel surface (catalyzing dechlorination
of the chlorohydrocarbons), by ionizing the carboxylic acid/other corrosive agents (zinc chloride used in brazing)] and by completing the electrical path of the electrochemical reaction in Step 5.
This system (the Strantrol 890 from Siemens Water Technologies), is an automated, demand-based online chlorination and dechlorination
control system that uses advanced High Resolution Redox[R] (HRR) technology.
During the dechlorination
process, diluted EOS is injected into the aquifer and followed with chase water to distribute and immobilize the oil droplets.
The success of bioremediation relies on the presence and activities of microorganisms that are capable of degrading TCE by catalyzing sequential dechlorination
reactions, thereby transforming trichloroethene (TCE) [right arrow] dichloroethene (DCE) [right arrow] vinyl chloride (VC) [right arrow] ethene (Hendrickson et al.
This versatile system features a reboil function, pilot light indicator, 98[degrees]C (205[degrees]F) "hold warm" feature, detachable safety plug, a 360-degree rotating base, automatic "no water" power-off and dechlorination
functions and three dispensing options, including auto dispense, manual dispense and cup-switch dispense.
of polychlorinated biphenyls in industrial transformer oil by radiolytic and photolytic methods, Environ.
The water in the buckets was tap water with aquarium-type dechlorination
It degrades mainly through dechlorination
and partly through a substitution reaction due to microbial action (Sato and Tanaka 1987).
Recent studies of H2 use in reductive dechlorination
show that dechlorinators have an affinity for H2 at least an order of magnitude greater than that of hydrogenotrophic methanogens.
