Heavy metal removal using nanoscale zero-valent iron (nZVI): Theory and application
Journal of Hazardous Materials, 2017Treatment of wastewater containing heavy metals requires considerations on simultaneous removal of different ions, system reliability and quick separation of reaction products. In this work, we demonstrate that nanoscale zero-valent iron (nZVI) is an ideal reagent for removing heavy metals from wastewater.

Enrichment of uranium from wastewater with nanoscale zero-valent iron (nZVI)
Environmental Science: Nano, 2021The core–shell structured nZVI not only can separate U(vi) from tailings wastewater, but also can enrich U in core area. Removal mechanisms include encapsulation, reduction, adsorption and precipitation.

The effects of the injection parameters on delivery of nanoscale zero-valent iron (NZVI) to contaminated groundwater were investigated. The first two NZVI injections (gravity injection at low flow rates) resulted in NZVI being poorly mobile and gave total cumulative mass recoveries at the monitoring wells of 1.07%-2.43%. NZVI reached some wells (KDMW-3,

Stabilization of biosolids with nanoscale zero-valent iron (nZVI)
Journal of Nanoparticle Research, 2007Biosolids are the treated organic residuals, also known as sludge, that are generated from domestic wastewater treatment plants. According to the USEPA, over 7 millions tons (dry weight) of biosolids are generated every year in the US by more than the 16,000 wastewater treatment plants and a large portion of these biosolids is disposed on land ...

Solvent-free production of nanoscale zero-valent iron (nZVI) with precision milling
Green Chemistry, 2009Despite its effectiveness in degrading a wide array of environmental contaminants and superior physical characteristics for subsurface delivery, large-scale applications of nanoscale zero-valent iron (nZVI) for environmental remediation have been inhibited by the high costs associated with its conventional production technologies. In this contribution,

The conventional carboxymethyl cellulose (CMC) stabilization hampered available active sites of adsorption and reduction, due to irregular shape of nanoscale zero-valent iron (nZVI) particles with augmented average size and passivated surface, leading to insufficient removal and poor resistance against complex environmental conditions.

Phytotoxicity and uptake of nanoscale zero-valent iron (nZVI) by two plant species
Science of The Total Environment, 2013Use of nano-scale zero valent iron (nZVI) for the treatment of various environmental pollutants has been proven successful. However, large scale introduction of engineered nanomaterials such as nZVI into the environment has recently attracted serious concerns.

Removal of Cr(VI) by Nanoscale Zero-valent Iron (nZVI) From Soil Contaminated with Tannery Wastes
Bulletin of Environmental Contamination and Toxicology, 2011The illegal disposal of tannery wastes at Rania, Kanpur has resulted in accumulation of hexavalent chromium [Cr(VI)], a toxic heavy metal in soil posing risk to human health and environment. 27 soil samples were collected at various depths from Rania for the assessment of Cr(VI) level in soil. Out of 27 samples, five samples had shown significant level
