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 ...

NITRATE REDUCTION USING SYNTHESIZED G--NZVI AND G--NZVI--CU PREPAREDFROM OPTIMIZED EXTRACTED POLYPHENOLS FROM SUGANDA LEAVES

Journal of BIMP-EAGA Regional Development, 2019
Polyphenols present in Suganda (Plectranthus amboinicus (Lour.) Spreng) extract can reduce the cationic iron to zero valent iron while simultaneously forming nanoparticles. The study involved the phenolic extraction at different solvent concentrations and temperatures.

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.

Inhibition of nZVI reactivity by magnetite during the reductive degradation of 1,1,1-TCA in nZVI/magnetite suspension

Applied Catalysis B: Environmental, 2010
Abstract We demonstrated that the reactivity of nano-sized zero-valent iron (nZVI) can be inhibited by magnetite for the reductive degradation of 1,1,1-trichloroethane (1,1,1-TCA) in nZVI/magnetite suspension under low content of nZVI. A remarkable reductive degradation of 1,1,1-TCA (0.289 h−1) was observed in nZVI (0.01 g/24 mL) suspension in 5 h ...

Comparison of characteristics of montmorillonite supported nano zero valent iron (M-nZVI) and nano zero valent iron (nZVI)

AIP Conference Proceedings, 2015
In this study, synthesized montmorillonite supported nano zero valent iron (M-nZVI) and nano zero valent iron (nZVI) are compared physically and chemically. The samples were prepared using chemical reduction method that includes sodium borohydride and ethanol.

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

Hydrogen Production by Formic Acid Decomposition with Nanoscale Zero-Valent Iron (nZVI): Effects of nZVI Dosage, Temperature and Time

Journal of Advanced Research in Fluid Mechanics and Thermal Sciences
Amidst growing interest in renewable hydrogen gas production, this paper examines three important parameters affecting hydrogen production via formic acid decomposition reaction with nanoscale zero-valent iron (nZVI). The study investigates variations in nZVI dosage (200 – 1000 g/L), reaction temperature (25 – 75°C), and reaction time (5 -30 minutes ...

A comparison between field applications of NZVI

2007
Despite the use of Nanoscale Zerovalent Iron (NZVI) for the remediation of contaminated aquifers was proposed more than 10 years ago, there’s a wide literature and a good market demand, its application is still limited. The aim of this study is to understand the reason why the number of full scale applications is so small and to systematizes the ...
