Development and Characterization of a Chloroethenes-Dechlorinating Consortium Using Gluconate as a Hydrogen Donor

Journal of Water and Environment Technology, 2020
To evaluate the effectiveness of gluconate as a potential hydrogen donor for reductive dechlorination of chloroethenes, we developed a trichloroethene (TCE)-dechlorinating consortium from chloroethenes-contaminated groundwater containing Dehalococcoides ...

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Ultrafast reductive dechlorination of carbon tetrachloride by amorphous Fe78Si9B13 alloy

Results in Physics, 2019
Amorphous Fe78Si9B13 ribbons and zero-valent iron (ZVI) powder were used to remove carbon tetrachloride (CTC) in the neutral oxic environment. The amorphous Fe78Si9B13 ribbons showed significantly better dechlorination performance than the ZVI powder ...

Temporal Evolution of Contaminant Mass Discharge: Effect of Source Remediation at Contaminated Sites

Groundwater Monitoring &Remediation, EarlyView.
Abstract Contaminant mass discharge (CMD) is a key metric for evaluating remediation performance at contaminated sites posing a risk to groundwater. This study assesses temporal CMD trends and associated uncertainties using a geostatistical approach at a chlorinated solvent contaminated site following source zone remediation, supported by two decades ...

Reductive dechlorination of tetrachloroethene by a stepwise catalysis of different organohalide respiring bacteria and reductive dehalogenases [PDF]

, 2018
The enrichment culture SL2 dechlorinating tetrachloroethene (PCE) to ethene with strong trichloroethene (TCE) accumulation prior to cis-1,2-dichloroethene (cis-DCE) formation was analyzed for the presence of organohalide respiring bacteria and reductive ...

Effect of cadmium on reductive dechlorination of trichloroaniline

, 1996
The effect of a transition metal, cadmium (Cd), on reductive dechlorination of a model chlorinated organic, 2,3,4-trichloroaniline (2,3,4- TCA), was determined in the laboratory in three anaerobic, flooded soils with varying properties. Dechlorination of

Temperature-associated effects on methanogenesis and microbial reductive dechlorination of trichloroethene in contaminated aquifer sediments

Frontiers in Water
BackgroundAquifer thermal energy storage (ATES) is a subsurface technology for urban heating and cooling. However, ATES systems may intersect with legacy groundwater contaminants from past anthropogenic activities.

Use of Polycyclic Aromatic Compounds as Electrophotocatalysts in Organic Reactions

Chemistry–Methods, Volume 6, Issue 11, November 2026.
Emerging from the convergence of photoredox catalysis and electrochemistry, electrophotocatalysis is a relatively new and promising synthetic approach in organic chemistry. In this review, the main advantages and the current challenges of this methodology are discussed, while most relevant and late applications of polycyclic aromatic hydrocarbons (PAHs)

Bioelectrochemical single reactor for reductive and oxidative removal of trichloroethylene from contaminated groundwater

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 11, Page 2268-2275, November 2026.
Abstract BACKGROUND Chlorinated aliphatic hydrocarbons such as trichloroethylene (TCE) are persistent groundwater contaminants due to improper disposal and low biodegradability. This work presents an innovative bioelectrochemical system for the integrated reductive/oxidative removal of TCE from contaminated water, implemented in a single tubular ...

Effects of Ferric Oxyhydroxide on Anaerobic Microbial Dechlorination of Polychlorinated Biphenyls in Hudson and Grasse River Sediment Microcosms: Dechlorination Extent, Preferences, Ortho Removal, and Its Enhancement

Frontiers in Microbiology, 2018
Microbial reductive dechlorination of polychlorinated biphenyls (PCBs) has been observed in many PCB-impacted sediments. However, this biodegradation is relatively site-specific and can be affected by PCB compositions and sediment geochemical conditions.
