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 ...

Removal of atrazine by nanoscale zero valent iron supported on organobentonite

Science of The Total Environment, 2011
The organobentonite (CTMA-Bent) was prepared from Na(+)-saturated bentonite (Na-Bent) by intercalation with cetyltrimethylammonium bromide (CTMA), and used as a carrier of nanoscale zero valent iron (NZVI) for the removal of atrazine. The NZVI/CTMA-Bent composite was characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM ...

Microwave-induced nanoscale zero-valent iron degradation of perchloroethylene and pentachlorophenol

Journal of the Air & Waste Management Association, 2012
Microwave (MW) is applied to enhance perchloroethylene (PCE) or pentachlorophenol (PCP) removal using zero-valent iron (ZVI; Fe(0)) as the dielectric medium. ZVI has a much higher dielectric loss factor (39.5) than other media; it is capable of absorbing MW radiation rapidly to speed up the release of electrons, leading to rises of the ZVI particle ...

Removal of Arsenic(III) from Groundwater by Nanoscale Zero-Valent Iron

Environmental Science & Technology, 2005
Nanoscale zero-valent iron (NZVI) was synthesized and tested for the removal of As(III), which is a highly toxic, mobile, and predominant arsenic species in anoxic groundwater. We used SEM-EDX, AFM, and XRD to characterize particle size, surface morphology, and corrosion layers formed on pristine NZVI and As(III)-treated NZVI.

Reduction of Cr(VI) by Urea-Dispersed Nanoscale Zero-Valent Iron

Journal of Nanoscience and Nanotechnology, 2015
Urea was used to disperse nanoscale zero-valent iron (NZVI) for reduction of Cr(VI) to Cr(III) in aqueous solution. Scanning electron microscope and fourier transform-infrared spectra investigations demonstrated that urea could effectively increase the dispersion of NZVI resulting in more effective reduction sites (ERS) for Cr(VI) ions.

Reducing As availability in calcareous soils using nanoscale zero valent iron

Environmental Science and Pollution Research, 2017
Different methods, including the use of nanoscale zero-valent iron (NZVI), have been used to treat arsenic (As)-contaminated environments, with much less data on the use of NZVI in arsenic-calcareous-polluted soils. Accordingly, two different experiments were conducted to investigate the effects of NZVI on the removal of As from three different ...

Dechlorination of short chain chlorinated paraffins by nanoscale zero-valent iron

Journal of Hazardous Materials, 2012
In this study, nanoscale zero-valent iron (NZVI) particles were synthesized and used for the reductive dehalogenation of short chain chlorinated paraffins (SCCPs) in the laboratory. The results show that the dechlorination rate of chlorinated n-decane (CP(10)) by NZVI increased with decreased solution pH.

Transport of Nanoscale Zero-Valent Iron in the Presence of Rhamnolipid

Science of The Total Environment
Nanoscale zero-valent iron (nZVI) particles have gained widespread use for in-situ treatment of various chlorinated hydrocarbons. Their non-toxic nature, affordability, and minimal maintenance requirements have made them a favored material for nanoremediation.

Nanoscale zero-valent iron reverses resistance of Pseudomonas aeruginosa to chloramphenicol

Journal of Hazardous Materials
Zero-valent iron (ZVI) has been extensively studied for its capacity to remove various contaminants in the environments. However, whether ZVI affects bacterial resistance to antibiotics has not been fully explored. Herein, it was unexpected that, compared with microscale ZVI (mZVI), nanoscale ZVI (nZVI) facilitated the susceptibility of Pseudomonas ...
