Combination of Electrokinetics and nZVI Remediation

2020
Electrogeochemical processes as a whole remedial technology have a considerable application potential. They may be applied at sites with complex geological conditions where hydraulic intervention is inefficient or unreliable. In the case of ClE remediation, electrochemical processes can substantially accelerate not only the time necessary for the ...

Groundwater geochemical constituents controlling the reductive dechlorination of TCE by nZVI: Evidence from diverse anaerobic corrosion mechanisms of nZVI

Chemosphere, 2021
The corrosion mechanisms of nanoscale zero-valent iron (nZVI) vary with different geochemical constituents, which affect the reductive dechlorination process of trichloroethylene (TCE). In this study, the effect of nZVI anaerobic corrosion on the reductive dechlorination of TCE with different groundwater geochemical constituents (Ca2+-SO42-, Ca2+-HCO3-,

Arsenic and chromium removal using nZVI particles and porous PLA/nZVI composites

Environmental resources, sustainable development and food production – OPORPH 2023: Book of Abstracts, 2023
Heavy metal pollution poses a great threat for the environment, especially for various bodies of water. Since certain industries produce heavy metals as a byproduct methods for their removal from industrial wastewaters are of huge importance. These inorganic pollutants are very dangerous for living organisms, effecting biological functions and causing ...

Using nZVI particles and hydrogel incorporated nZVI for amoxicillin removal

2023
Antibiotics have become a great environmental issue of modern world. Their concentrations are gradually rising in wastewater and ground water where they are imposing a risk for aquatic and terrestrial organisms. Various methods for pharmaceutical wastewater treatment including adsorption, filtration and advanced oxidation processes (AOP) have already ...

Characterization of nZVI Mobility in a Field Scale Test

Environmental Science & Technology, 2014
Nanoscale zerovalent iron (nZVI) particles were injected into a contaminated sandy subsurface area in Sarnia, Ontario. The nZVI was synthesized on site, creating a slurry of 1 g/L nanoparticles using the chemical precipitation method with sodium borohydride (NaBH4) as the reductant in the presence of 0.8% wt. sodium carboxymethylcellulose (CMC) polymer

Toxicity of nZVI in the growth of bacteria present in contaminated soil

Chemosphere, 2022
The use of nano zero-valent iron (nZVI) for the remediation of degraded areas is a consolidated practice. However, the long-term reactions that occur in the environment remain unknown. This study aimed to evaluate the potential toxic effects on the growth of colony-forming units (CFUs) of Bacillus cereus and Pseudomona aeruginosa present in soil ...

Impact of nZVI stability on mobility in porous media

Journal of Contaminant Hydrology, 2013
Nano-scale zero valent iron (nZVI) has received significant attention because of its potential to rapidly reduce a number of priority source zone contaminants. In order to effectively deliver nZVI to the source zone the nZVI particles must be stable.

Unveiling the Differential Impacts of S-nZVI and nZVI on Microbial Dechlorination of Trichloroethene by Dehalococcoides

Environmental Science & Technology
Sulfidated nanoscale zerovalent iron (S-nZVI) is a promising material for the remediation of chlorinated hydrocarbons (CHCs) in groundwater, offering enhanced reactivity and selectivity over unmodified nanoscale zerovalent iron (nZVI). However, integrating S-nZVI with bioremediation using organohalide-respiring bacteria (OHRB) poses potential ...
