Investigations on mobility of carbon colloid supported nanoscale zero-valent iron (nZVI) for groundwater remediation
Injection of nanoscale zero-valent iron (nZVI) is an innovative technology for in situ installation of a permeable reactive barrier in the subsurface. Zerovalent iron (ZVI) is highly reactive with chlorinated hydrocarbons (CHCs) and renders them into less harmful substances. Application of nZVI …

Consumers and Their Drinking Water: Communicating Water Quality and Assessing the Reaction of Zerovalent Nanoiron (nZVI) with Saliva
… to measure reaction of zerovalent nanoiron (nZVI) in water and human saliva, evaluate consumer's perceptions of taste, odor, and risk in their drinking water, and investigate the effectiveness of community water systems in communicating water quality information to their consumers. Since …

Hydraulic and Electrokinetic Delivery of Remediants for In-situ Remediation
Nano-scale zero valent iron (nZVI) has shown promising mobility and in-situ reactivity with chlorinated volatile organic compounds when injected into saturated porous media. The current study evaluated nZVI mobility and subsequent reactivity with in-situ contaminants in a variably saturated porous …

Removal of nitrate from contaminated groundwater by floating alginate beads
… effectiveness of zero valent iron nanoparticles (NZVI) and magnetite nanoparticles (MNP) in converting nitrate to ammonium. However, the fate of nitrate after its transformation to ammonium has remained an unanswered question. Many of the previous studies have also neglected the possibility of the …

Enhanced Dechlorination of 1,2-Dichloroethane by Coupled Nano Iron-Dithionite Treatment
… experiments combining bimetallic or monometallic nZVI (stabilized or non-stabilized) with sodium dithionite were conducted for the degradation of 1,2-DCA. These experiments have yielded up to 92 % degradation of the initial 1,2-DCA concentration over the course of a year. Observed pseudo-first …

Hydrogen Gas Production and Effects During Remediation Using Nano-scale Zero-valent Iron
… exsolution during nanoscale zero-valent iron (nZVI) groundwater remediation applications. An improved understanding of gas exsolution and its effects can be applied to remediation technologies that produce gas in excess of solubility limits, including bioremediation and nZVI. Experiments were …

Impact of metallic nanoparticles on anaerobic digestion
… consumer products while nano zero valent iron (NZVI) has been proposed for site remediation and industrial wastewater treatment. In batch anaerobic digestion systems, AgNPs at the concentration of 40 mg/L did not inhibit methane production, as more than 90% of AgNPs were removed from the liquid …

Fate and Impacts of Contaminants of Emerging Concern during Wastewater Treatment
… Effects of silver (nanoAg), zero-valent iron (NZVI), titanium dioxide (nanoTiO2) and cerium dioxide (nanoCeO2) nanomaterials on nitrification function and microbial communities were examined in duplicate lab-scale nitrifying sequencing batch reactors (SBRs), relative to control SBRs received no …

Characterization of Metallic Flavor in Drinking Water: An Interdisciplinary Exploration through Sensory Science, Medicine, Health, and the Environment
… properties of zerovalent iron nanoparticles (nZVI) indicated that oral exposure to nZVI may induce sensory properties different from that of ferrous iron, likely predictive of a diminished detection of metallic flavor by humans. Further research is warranted in this area.

Novel treatment technologies for arsenic removal from water
… arsenite. By adding nanoscale zero valent iron (nZVI) of 0.05 g/L in the photo reactor, arsenic removal can be significantly enhanced to a value less than 10 μg/L. The amount of TiO2 used in this photocatalysis hybrid system was only 20% of normal photocatalysis operation. Removal of arsenic by a …
