Degradation of chlorinated phenols by nanoscale zero-valent iron

Frontiers of Environmental Science & Engineering in China, 2008
Chlorophenols (CPs), as important contaminants in groundwater, are toxic and difficult to biodegrade. Recently nanoscale zero-valent iron received a great deal of attention because of its excellent performance in treating recalcitrant compounds.

Stabilization of biosolids with nanoscale zero-valent iron (nZVI)

Journal of Nanoparticle Research, 2007
Biosolids 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 ...

Study on Cytotoxicity of Nanoscale Zero Valent Iron Particles

Materials Science Forum, 2011
Although small nZNI nanoparticles are useful in various applications, the biosafety of this material needs to be evaluated. In this study, Escherichia coli cells were exposed to 0, 112, 560, 1120 mg/L of nano-Fe0particles, respectively. Experiments were carried out to examine the activities of lactate dehydrogenase (LDH), cellular superoxide dismutase (

Recovery of indium ions by nanoscale zero-valent iron

Journal of Nanoparticle Research, 2017
Indium and its compounds have plenty of industrial applications and high demand. Therefore, indium recovery from various industrial effluents is necessary. It was sequestered by nanoscale zero-valent iron (nZVI) whose size mainly ranged from 50 to 70 nm. Adsorption kinetics and isotherm, influence of pH, and ionic strength were thoroughly investigated.

Performance of Bimetallic Nanoscale Zero-Valent Iron Particles for Removal of Oxytetracycline

Journal of Environmental Sciences, 2018
In this study, bimetallic nanoscale zero-valent iron particles (nZVI), including copper/nanoscale zero-valent iron particles (Cu/nZVI) and nickel/nanoscale zero-valent iron particles (Ni/nZVI), were synthesized by one-step liquid-phase reduction and applied for oxytetracycline (OTC) removal.

Removal of Antibiotic Florfenicol by Sulfide-Modified Nanoscale Zero-Valent Iron

Environmental Science & Technology, 2017
Florfenicol (FF, C12H14Cl2FNO4S), an emerging halogenated organic contaminant of concern was effectively degraded in water by sulfidized nanoscale zerovalent iron (S-nZVI). Sulfidized nZVI (62.5 m2 g-1) that was prepared using a one-step method resulted in small Fe0/Fe-sulfide particles that were more stable against aggregation than unsulfidized nZVI ...

Effect of nanoscale zero-valent iron confined in mesostructure on Escherichia coli

Environmental Science and Pollution Research, 2017
Nanoscale zero-valent iron particles (NZVIs) confined in the mesochannels of SBA-15 have superabilities in the remediation of contaminated groundwater. As a new kind of remediation nanomaterials, it is necessary to investigate the ecotoxicity of NZVIs/SBA-15 composites during their applications.

Nanoencapsulation of arsenate with nanoscale zero-valent iron (nZVI): A 3D perspective

Science Bulletin, 2018
The principal forces driving the efficient enrichment and encapsulation of arsenic (As) into nanoscale zero-valent iron (nZVI) are the disordered arrangement of the atoms and the gradient chemical potentials within the core-shell interface. The chemical compositions and the fine structure of nZVI are characterized with a combination of spherical ...

Dechlorination of Excess Trichloroethene by Bimetallic and Sulfidated Nanoscale Zero-Valent Iron

Environmental Science & Technology, 2018
Nanoscale zerovalent iron (nZVI) likely finds its application in source zone remediation. Two approaches to modify nZVI have been reported: bimetal (Fe-Me) and sulfidated nZVI (S-nZVI). However, previous research has primarily focused on enhancing particle reactivity with these two modifications under more plume-like conditions.
