Enhanced Leaching of Zinc Ferrite by the Formation of a Solid Solution With Magnetite in Hydrochloric Acid Solution

The high zinc and iron contents of electric arc furnace (EAF) dust in the forms of zinc ferrite (ZnFe2O4) and magnetite (Fe3O4) make it a valuable secondary source of these metals. ZnFe2O4 and Fe3O4 are known to form a solid solution at all compositions, a ...

Biostimulation as a sustainable solution for acid neutralization and uranium immobilization post acidic in-situ recovery

Rizlan Bernier-Latmani, Pierre Rossi, Thomas Coral

Major uranium (U) deposits worldwide are exploited by acid leaching, known as 'in-situ recovery' (ISR). ISR involves the injection of an acid fluid into ore-bearing aquifers and the pumping of the resulting metal-containing solution through cation exchange ...

Insights into the microbial reduction of pentavalent and hexavalent uranium species by Shewanella oneidensis MR-1

Margaux Camille Andréa Molinas

Decades of uranium-related activities such as ore mining, nuclear power generation, weapon manufacture, storage of nuclear wastes, have contributed to the release of U in the environment. U occurrence is concerning, since in surface environments, U is typi ...

In Situ Biostimulation of Cr(VI) Reduction in a Fast-Flowing Oxic Aquifer

Rizlan Bernier-Latmani, Daniel Scott Alessi

Hexavalent chromium is among the most common and hazardous inorganic contaminants in soils and groundwater. A promising in situ bioremediation approach is the delivery of electron donors to stimulate microbially mediated Cr(VI) reduction, producing relativ ...

Impact of iron- and/or sulfate-reduction on a cis-1,2-dichloroethene and vinyl chloride respiring bacterial consortium: experiments and model-based interpretation

Christof Holliger, Julien Maillard, Alexandra Marie Murray

Process understanding of microbial communities containing organohalide-respiring bacteria (OHRB) is important for effective bioremediation of chlorinated ethenes. The impact of iron and sulfate reduction on cis-1,2-dichloroethene (cDCE) and vinyl chloride ...

As release under the microbial sulfate reduction during redox oscillations in the upper Mekong delta aquifers, Vietnam: A mechanistic study

Rizlan Bernier-Latmani, Manon Frutschi, Laurent Louis José Charlet

The impact of seasonal fluctuations linked to monsoon and irrigation generates redox oscillations in the subsurface, influencing the release of arsenic (As) in aquifers. Here, the biogeochemical control on As mobility was investigated in batch experiments ...

An ecological approach for understanding the reductive dechlorination process of chlorinated ethenes in contaminated aquifers

Christof Holliger, Pierre Rossi, Sonia Estelle Tarnawski

Chlorinated ethenes, frequently encountered contaminants in groundwater, are often found to be incompletely dechlorinated to dichloroethene and vinyl chloride, more toxic products that accumulate in the aquifer. Some of the concerns in designing remediatio ...

Catalysis at room temperature ionic liquid|water interface: H2O2 generation

Hubert Girault, Gunther Wittstock

H2O2 is produced at the interface between a room-temperature ionic liquid with decamethylferrocene as electron donor and an acidic aqueous solution. The electron donor can be regenerated electrochemically. ...

Assessment of bioremediation potential and monitoring of biological reductive dechlorination in sites contaminated with chlorinated ethenes

Christof Holliger, Pierre Rossi, Sonia Estelle Tarnawski

Chlorinated ethenes (CEs), such as perchloroethene (PCE) and trichloroethene, are one of the most common classes of groundwater contaminants. In this project, the contaminant biodegradation capacities of two aquifers, presenting both dichloroethene (DCE) a ...
