Zero-Valent Iron for Water Treatment

Environmental Technology, 2000
The use of zero-valent iron in the treatment of hazardous water contaminants is reviewed. The review concentrates on experimental procedures employed in the investigation of a range of applications for zero -valent iron and the efficacy of the processes.

Zero-Valent Iron-Assisted Autotrophic Denitrification

Journal of Environmental Engineering, 2005
Porous reactive barriers containing metallic iron and hydrogenotrophic denitrifying microorganisms may potentially be suitable for in-situ remediation of nitrate-contaminated groundwater resources. The main objective of the research described here was to determine the type and concentration of metallic iron to be used in such reactive barriers so that ...

Fenton's oxidation of MTBE with zero-valent iron

Water Research, 2004
Methyl tert-butyl ether (MTBE) has become a contaminant of increasing concern in the U.S. Traditional remediation technologies are successful in removing MTBE from contaminated water, but usually transfer the contaminant from the aqueous to another phase.

Reduction of nitroaromatic pesticides with zero-valent iron

Chemosphere, 2004
Reduction of eleven nitroaromatic pesticides was studied with zero-valent iron powder. Average half-lives ranged from 2.8 to 6.3 h and the parent compounds were completely reduced after 48-96 h. The di-nitro groups of the 2,6-dinitroaniline herbicides were rapidly reduced to the corresponding diamines, with a negligible amount of partially reduced ...

Nitrate removal in zero-valent iron packed columns

Water Research, 2003
Nitrate removal by laboratory and field continuous-flow zero-valent iron (Fe(0)) packed bed columns was evaluated for different influent water qualities (pH, dissolved oxygen (DO), nitrate concentration) and several months of operation (600-1500 bed volumes (BVs)).

Zero-Valent Iron-Promoted Dechlorination of Polychlorinated Biphenyls

Environmental Science & Technology, 1995
Zero-valent iron promoted the dechlorination of PCBs (Aroclors 1221 and 1254) at elevated temperatures in an oxygen-limited environment. At temperatures higher than 300{degrees}C, dechlorination of Aroclor 1221 began to occur; at 400{degrees}C, the major reaction product, biphenyl, was observed in highest yield.

Treatment of Distillery Wastewater by the Nano‐Scale Zero‐Valent Iron and the Supported Nano‐Scale Zero‐Valent Iron

Water Environment Research, 2011
The treatment of wastewater from the distillery industry was carried out by using nano‐scale‐ and supported nano‐scale zero‐valent iron at a laboratory scale and ambient temperature. Effects of dilution, pH, mixing rate, zero‐valent iron dosage, and amount of support for the zero‐valent iron were investigated. All parameters had a significant effect on

Development of stabilized zero valent iron nanoparticles

DESALINATION AND WATER TREATMENT, 2012
Abstract Many organic micropollutants have recently been identified in natural water sources and treated drinking water. Often, these compounds are not successfully degraded or removed by current water treatment processes. There is an increasing interest in developing new water treatment technologies based on catalytic nanoparticles to take advantage ...

Dechlorination of Hexachlorobenzene by Zero-Valent Iron

Practice Periodical of Hazardous, Toxic, and Radioactive Waste Management, 2004
Chemical reduction of hexachlorobenzene (HCB) by metallic iron was investigated. Since the percentage of HCB transformation is almost the same as that of chloride ion production, no chlorinated intermediates in the solution was formed during the reduction reaction.

Textile wastewater decolorization by zero valent iron activated peroxymonosulfate: Compared with zero valent copper

Journal of Environmental Chemical Engineering, 2014
Abstract Textile wastewater must be decolorized before discharging into the environment. In this study, peroxymonosulfate (PMS) was activated by zero valent iron (ZVI) to produce sulfate radical for degradation of organic compounds. The optimum condition for activation of PMS was provided in pH of 4 and 3000 mg/L ZVI.
