Intermittent Oxygen Supply Facilitates Codegradation of Trichloroethene and Toluene by Anaerobic Consortia.

Environmental Science and Technology, 2023
Biodegradation is commonly employed for remediating trichloroethene- or toluene-contaminated sites. However, remediation methods using either anaerobic or aerobic degradation are inefficient for dual pollutants. We developed an anaerobic sequencing batch

A Synergistic Platform for Continuous Co-removal of 1,1,1-Trichloroethane, Trichloroethene, and 1,4-Dioxane via Catalytic Dechlorination Followed by Biodegradation.

Environmental Science and Technology, 2021
Groundwater co-contaminated with 1,4-dioxane, 1,1,1-trichloroethane (TCA), and trichloroethene (TCE) is among the most urgent environmental concerns of the U.S. Department of Defense (DoD), U.S.

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 ...

Long-Term Continuous Co-reduction of 1,1,1-Trichloroethane and Trichloroethene over Palladium Nanoparticles Spontaneously Deposited on H2-Transfer Membranes.

Environmental Science and Technology, 2020
1,1,1-Trichloroethane (1,1,1-TCA) and trichloroethene (TCE) are common recalcitrant contaminants that coexist in groundwater. H2-induced reduction over precious-metal catalysts has proven advantageous, but its application to long-term continuous ...

Cometabolic degradation of toxic trichloroethene or cis-1,2-dichloroethene with phenol and production of poly-β-hydroxybutyrate (PHB)

, 2021
Trichloroethene (TCE) and cis-1,2-dichloroethene (cDCE) are volatile organic compounds (VOCs) that are ubiquitous in the environment and cause health concerns.

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.

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

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

Kinetics of trichloroethene dechlorination with iron powder

Water Research, 2005
The dechlorination of trichloroethene (TCE) with metallic iron is an advantageous method for the remediation of contaminated groundwater and soil. The toxic reaction intermediates such as dichloroethenes (DCEs) and vinyl chloride (VC), however, occasionally accumulate in the pathway of the reaction.
