Modeling arsenic removal by nanoscale zero-valent iron
Environmental Monitoring and Assessment, 2020Arsenic removal by nanoscale zero-valent iron (NZVI) was modeled using the USGS geochemical program PHREEQC. The Dzombak and Morel adsorption model was used. The adsorption of As(V) onto NZVI was assumed to happen because of the hydrous ferric oxide (Hfo) which was the surface oxide for the model.

Zero-valent iron pretreatment for enhancing the biodegradability of RDX
Water Research, 2005Hexahydro-1,3,5-trinitro-1,3,5-triazine (C3H6N3(NO2)3, royal demolition explosive or RDX) is a common nitramine explosive and one of the major constituents in wastewaters from ammunitions plants. The objective of this study is to investigate zero-valent iron (Fe0) pretreatment for enhancing the biodegradability of recalcitrant RDX.

Kinetics of reductive denitrification by nanoscale zero-valent iron
Chemosphere, 2000Zero-valent iron powder (Fe0) has been determined to be potentially useful for the removal of nitrate in the water environment. This research is aimed at subjecting the kinetics of denitrification by nanoscale Fe0 to an analysis of factors affecting the chemical denitrification of nitrate.

Zero-Valent Iron-Promoted Dechlorination of Polychlorinated Biphenyls
Environmental Science & Technology, 1995Zero-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.

Kinetics of RDX degradation by zero-valent iron (ZVI)
Journal of Hazardous Materials, 2006Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) is a common groundwater contaminant at military facilities. The current research has been conducted to evaluate the use of zero-valent iron (ZVI) for the remediation of water contaminated with RDX. RDX was found to degrade rapidly in the presence of ZVI.

Impact of zero valent iron on blackwater anaerobic digestion
Bioresource Technology, 2019The source diverted blackwater treatment is receiving growing attention as an alternative to conventional energy intensive wastewater management and treatment systems. Blackwater, containing concentrated organic materials, can be anaerobically digested to recovery bioenergy.

Reduction of trichloroethylene and nitrate by zero-valent iron with peat
Journal of Environmental Science and Health, Part A, 2008The feasibility of using zero-valent iron (ZVI) and peat mixture as in situ barriers for contaminated sediments and groundwater was investigated. Trichloroethylene (TCE) and nitrate (NO(3)(-)), redox sensitive contaminants were reduced by ZVI and peat soil mixture under anaerobic condition.

Nitrate removal in zero-valent iron packed columns
Water Research, 2003Nitrate 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)).
