Bactericidal effect of zero-valent iron nanoparticles on Escherichia coli.
Zero-valent iron nanoparticles (nano-Fe0) in aqueous solution rapidly inactivated Escherichia coli. A strong bactericidal effect of nano-Fe0 was found under deaerated conditions, with a linear correlation between log inactivation and nano-Fe0 dose (0.82 log inactivation/mg/L nano-Fe0 x h). The inactivation of E. coli under air saturation required much higher nano-Fe0 doses due to the corrosion ...
متن کاملCharacterization of zero-valent iron nanoparticles.
The iron nanoparticle technology has received considerable attention for its potential applications in groundwater treatment and site remediation. Recent studies have demonstrated the efficacy of zero-valent iron nanoparticles for the transformation of halogenated organic contaminants and heavy metals. In this work, we present a systematic characterization of the iron nanoparticles prepared wit...
متن کاملTwo dimensional transport characteristics of surface stabilized zero-valent iron nanoparticles in porous media.
Zero-valent iron nanoparticles (INP) were synthesized and stabilized using poly acrylic acid (PAA) to yield stabilized INP (S-INP). A two-dimensional physical model was used to study the fate and transport of the INP and S-INP in porous media under saturated, steady-state flow conditions. Transport data for a nonreactive tracer, INP, and S-INP were collected under similar flow conditions. The r...
متن کاملDegradation of Lindane by Zero-Valent Iron Nanoparticles
Thus far, zero-valent iron has been studied mostly for the degradation of structurally simple oneand two-carbon halogenated organic contaminants such as chlorinated methanes, ethanes, and ethenes. In this research, laboratory synthesized particles of nanoscale iron were explored to degrade lindane, also known as -hexachlorocyclohexane, a formerly widely utilized pesticide and well-documented pe...
متن کاملAntimicrobial and Genotoxicity Effects of Zero-valent Iron Nanoparticles
BACKGROUND In a world of nanotechnology, the first concern is the potential environmental impact of nanoparticles. An efficient way to estimate nanotoxicity is to monitor the responses of bacteria exposed to these particles. OBJECTIVES The current study explored the antimicrobial properties of nZVI (zero-valent Iron nanoparticles) on the Gram-negative bacterial systems Erwinia amylovora, Xant...
