Abiotic reductive dechlorination of chlorinated ethylenes by soil.
Abiotic reductive dechlorination of chlorinated ethylenes by soil in anaerobic environments was characterized to improve knowledge of the behavior of chlorinated ethylenes in natural systems, including systems modified to promote attenuation of contaminants. Target organics in the soil suspension reached sorption equilibrium in 2 days and the sorption isotherm of target organics was properly de...
متن کاملAbiotic reductive dechlorination of chlorinated ethylenes by iron-bearing phyllosilicates.
Abiotic reductive dechlorination of chlorinated ethylenes (tetrachloroethylene (PCE), trichloroethylene (TCE), cis-dichloroethylene (c-DCE), and vinylchloride (VC)) by iron-bearing phyllosilicates (biotite, vermiculite, and montmorillonite) was characterized to obtain better understanding of the behavior of these contaminants in systems undergoing remediation by natural attenuation and redox ma...
متن کاملKinetics and inhibition of reductive dechlorination of chlorinated ethylenes by two different mixed cultures.
Kinetic studies with two different anaerobic mixed cultures (the PM and the EV cultures) were conducted to evaluate inhibition between chlorinated ethylenes. The more chlorinated ethylenes inhibited the reductive dechlorination of the less chlorinated ethylenes, while the less chlorinated ethylenes weakly inhibited the dechlorination of the more chlorinated ethylenes. Tetrachloroethylene (PCE) ...
متن کاملDechlorination of chlorinated ethylenes by a photochemically generated iron(0) complex.
The reactivity of Fe(0) toward chlorinated ethylenes was examined utilizing a photochemically generated, highly reactive Fe(0) complex. Irradiation of (dmpe)2FeH2 (dmpe = Me2PCH2CH2PMe2) with 360 nm light generated a 16-e(-), Fe(0) intermediate that reacted to dechlorinate chlorinated ethylenes in a stepwise fashion, consistent with a hydrogenolysis dechlorination pathway. The source of the hyd...
متن کاملIrreversible binding of chlorinated ethylenes to macromolecules
Rats have been exposed in a closed system to the chlorinated ethylenes vinyl chloride and trichloroethylene and to carbon tetrachloride as a reference compound. Data of uptake of the compounds, of urinary excretion of metabolites, and of exhalation after exposure show that the chlorinated ethylenes are metabolized much faster than carbon tetrachloride, probably due to their common ethylene stru...
