The excess enthalpy of (trichloroethene + carbon disulphide), (trichloroethene + trichloromethane), and (trichloroethene + tetrachloromethane) at various temperatures and pressures

The Journal of Chemical Thermodynamics, 1986
Abstract The excess molar enthalpies of (trichloroethene + carbon disulphide) at 293.15 K (0.1, 15.0, and 30.0 MPa) and 303.15 K (0.1 and 15.0 MPa), of (trichloroethene + trichloromethane) at 293.15 K (0.1, 15.0, and 30.0 MPa) and 303.15 K (0.1 MPa), and of (trichloroethene + tetrachloromethane) at 293.15 K (0.1, 15.0, and 30.0 MPa) have been ...

Kinetics of the depletion of trichloroethene.

Environmental Science & Technology, 1987
The depletion of trichloroethene (TCE) was studied in microcosms containing water and three types of natural sediment ranging in composition from highly organic to a calcareous sedimentary rock. The depletion rates varied slightly in the different sediments.

Electrically induced reduction of trichloroethene in clay

Journal of Hazardous Materials, 2010
Chlorinated compounds such as trichloroethene (TCE) are recalcitrant contaminants commonly detected in soil and groundwater. Contemporary remedies such as electron donor amendment tend to be less or ineffective in treating chlorinated compounds in matrix of lower permeability, such as clay. In this study, electrically induced reduction (EIR) was tested

Pyrite-assisted degradation of trichloroethene (TCE)

Chemosphere, 2001
Chemical kinetics of trichloroethene (TCE) degradation by pyrite was investigated at different experimental conditions. The TCE was transformed into C2H2, 1,1-dichloroethene (DCE) and C2H4 by a slow process (240 h required to convert TCE by 80%). Thereafter, the degradation rate showed a monotonous increase with the pH.

BIOTRANSFORMATION OF TRICHLOROETHENE IN A VARIETY OF SUBSURFACE MATERIALS

Environmental Toxicology and Chemistry, 1987
Abstract The abilities of three types of sediment to biotransform trichloroethene (TCE) were compared to determine the influence of environmental factors that differ among sediments of different composition. The results could suggest TCE behavior at spill sites in a variety of subsurface materials.

Movement of trichloroethene in a discontinuous permafrost zone

Journal of Contaminant Hydrology, 2011
At a site with discontinuous permafrost in Fairbanks, Alaska, releases of trichloroethene (TCE), an industrial solvent, have caused contamination of the groundwater. The objective of this study was to investigate the relationship between the migration pathway of the TCE groundwater plume and the distribution of the discontinuous permafrost at the site.

Adsorption of Trichloroethene at the Vapor/Water Interface

Environmental Science & Technology, 2000
Aqueous solution surface tension (pressure) as a function of vapor-phase trichloroethene (TCE) pressure isotherms were measured at atmospheric pressure at 287.2, 291.2, 297.2, 303.2, and 315.2 K using a flow-through vapor adsorption method. Solute (i.e., TCE)-induced surface tension variations were quantified using Axisymmetric Drop Shape Analysis ...

Sorption equilibria for trichloroethene on algae

Water Research, 1990
Abstract The sorption of chlorinated solvents by algae can remove the solvents from natural waters and wastewaters treated in stabilization lagoons and other phototrophically active treatment processes. The equilibrium sorption of 14 C-labeled trichloroethene (TCE) to three species of algae— Chlorella vulgaris , Scenedesmus quadricauda and ...

Sulfidation of Magnetite for Superior Dechlorination of Trichloroethene

Environmental Science & Technology
The reported contributions of magnetite to the abiotic natural attenuation of chlorinated ethenes have generated interest in its potential for soil and groundwater remediation. In this study, we investigated the impact of the two-step sulfidation method on the physicochemical properties and reactivity of magnetite with trichloroethene (TCE).

Sorption of trichloroethene onto stylolites

Journal of Contaminant Hydrology, 1999
Abstract Batch and double reservoir diffusion cell experiments are used to investigate sorption of trichloroethene onto stylolites. Stylolites are common features in carbonate rock formations, and might contain high amounts of organic matter. Due to the hydrophobic character of TCE, its transport in fractured carbonate aquifers could be significantly
