The study on the dechlorination of OCDD with Pd/C catalyst in ethanol-water solution under mild conditions

open access: yes, 2007
Dechlorination of octachlorodibenzo-p-dioxin (OCDD) was carried out in ethanol-water (v/v = 1:1) solution of NaOH in the presence of Pd/C catalysts with the use of H-2. The substrate was dechlorinated with Pd/C under mild conditions (atmospheric pressure

Inhibitory Effects of Sulfate and Nitrate Reduction on Reductive Dechlorination of PCP in a Flooded Paddy Soil

open access: yesFrontiers in Microbiology, 2018
Pentachlorophenol (PCP) is highly toxic and persistent in soils. Bioreduction of PCP often co-occurs with varying concentrations of sulfate and nitrate in flooded paddy soils where each can act as an electron acceptor.

Na2S-Mediated One-Pot Selective Deoxygenation of α-Hydroxyl Carbonyl Compounds including Natural Products

open access: yesMolecules, 2022
A practical method for the deoxygenation of α-hydroxyl carbonyl compounds under mild reaction conditions is reported here. The use of cheap and easy-to-handle Na2S·9H2O as the reductant in the presence of PPh3 and N-chlorosuccinimide (NCS) enables the ...

Visible-light-sensitized dechlorination of perchloroethylene

open access: yes, 2014
[[abstract]]An aqueous reaction mixture containing perchloroethylene (PCE), a photosensitizer, and an electron donor was irradiated by visible lamps to facilitate a sunlight-sensitized dechlorination reaction. Various types of lamps, electron donors, and

Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste

open access: yesAdvanced Science, EarlyView.
Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...

Dechlorination of Hexachloroethane in Water Using Iron Shavings and Amended Iron Shavings: Kinetics and Pathways

open access: yesJournal of Chemistry, 2014
In contrast to previous studies which employed zero-valent iron powder, this paper investigated reductive dechlorination of hexachloroethane (HCA) using iron shavings and bimetallic iron shavings modified with Cu, Ag, or Pd.

The Dechlorination of Hydrocarbons

open access: yesPlatinum Metals Review, 1997
The pollution of groundwater and soils by industrial chemicals is a cause of significant environmental concern. Treatment with palladium is suggested as a means of decontaminating certain occurrences of polluted soil and groundwater. Palladium can be chemically deposited onto zero-valence iron (Fe 0

Anaerobic bacteria that dechlorinate perchloroethene [PDF]

open access: yesApplied and Environmental Microbiology, 1987
In this study, we identified specific cultures of anaerobic bacteria that dechlorinate perchlorethene (PCE). The bacteria that significantly dechlorinated PCE were strain DCB-1, an obligate anaerobe previously shown to dechlorinate chlorobenzoate, and two strains of Methanosarcina.

Methanosarcina spp. drive vinyl chloride dechlorination via interspecies hydrogen transfer [PDF]

open access: yes, 2006
Two highly enriched cultures containing Dehalococcoides spp. were used to study the effect of aceticlastic methanogens on reductive vinyl chloride (VC) dechlorination. In terms of aceticlastic methanogens, one culture was dominated by Methanosaeta, while

Electrocatalytic dechlorination of p-chlorophenol using a 3D cathode with magnetic separable Fe3O4@PPy@Pd catalyst

open access: yesInternational Journal of Electrochemical Science, 2019
The magnetic separable catalyst, Fe3O4@PPy@Pd, was successfully prepared and characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and inductively coupled plasma- atomic emission spectroscopy (ICP-AES).
