  • Adobe PDF LogoAssessing the Use and Application of Zero-Valent Iron Nanoparticle Technology for Remediation at Contaminated Sites

    This document was prepared by Sean M. Cook, a NNEMS grantee under a fellowship from the EPA. The main focus of this paper is discussing the use of zero-valent iron nanoparticles. Due to its unique properties, this manufactured nanoparticle is able to effectively eliminate or neutralize certain recalcitrant pollutants that can be found in aquatic environments (e.g., groundwater aquifers). nZVI particles are typically 5-40 nm sized Fe0/Fe-oxide particles that rapidly transform many environmental contaminants to benign products and are a promising in Situ remediation agent. Due to their small size and increased reactivity, these manufactured nanoparticles have the potential to be more effective than the microscale ZVI that is already in use for contaminant remediation in soil and groundwater aquifers. However, little is known about the environmental fate of these nanomaterials once they have undergone biological and non-biological processes within a contaminated aquifer. For this reason, it is important to find out what the possible impacts of these nanomaterials are once they enter the environment and how they could potentially affect human health or the environment. Despite these concerns, nZVI technology and its application are a very promising, efficient and cost-effective method for remediating contaminated soil and groundwater aquifer sites.

  • Adobe PDF LogoFate, Transport, and Toxicity of Nanoscale Zero-Valent Iron (nZVI) Used During Superfund Remediation

    This document was prepared by Emily Keane, a NNEMS grantee under a fellowship from the EPA. The goal of this document is to provide information about the fate, transport, and toxicity associated with the use of nZVI for Superfund remediation. Specific and unique site conditions are likely to determine the usefulness and influence the fate and transport of nZVI particles during remediation efforts. Factors to consider prior to application include: effects of geochemistry on the mobility of nanoparticles, use of metal catalysts and coatings on the movement of nZVI particles and other variables affecting the fate and transport of nZVI in the environment. Other considerations include potential environmental and human health effects as a result of the fate and transport of nZVI in the environment.

    The application of nanotechnology or nano-enabled processes for the remediation of radionuclides hasn't been developed as much as the use of nanoscale materials for other contaminants. In this report, the development of nanotechnology applications for remediation of radionuclides and heavy metals are divided into two areas: new remediation methods and advancements in sensors. Though developments in these fields still remain in their early stages, this report describes some of the more promising remediation nanotechnologies and new sensors, and attempts to extrapolate general developments in nanotechnologies to advances in radionuclide remediation and monitoring.

  • Multifunctional Colloidal Particles for in Situ Remediation of Chlorinated Hydrocarbons

    The remediation of dense nonaqueous phase liquids (DNAPLs) can take place via in Situ injection technology however the process requires the use of decontamination agents that effectively migrate through the soil media and react efficiently with the contamination. This article describes the use of a decontamination system containing highly uniform carbon microspheres that are enveloped in a polyelectrolyte to which a bimetallic nanoparticle system of zero-valent iron and Pd is attached. The multifunctional systems appear to satisfy criteria related to remediation and are made with potentially environmentally benign materials.

  • Degradation of Trichloroethylene (TCE) by Nanoscale Zero-Valent Iron (nZVI) Immobilized in Alginate Bead

    Nowadays, many researchers have studied the environmental application of the nZVI and several field applications for the groundwater remediation have been reported. Still, there are many concerns on the fate and transport of the nZVI and the corresponding risks. To avoid such concerns, the investigator immobilized nZVI in a support and then it was applied to degrade trichloroethylene (TCE). The nZVI and palladium-doped nZVI (Fe(0)- and Fe/Pd-alginate) were immobilized in the alginate bead where ferric and barium ions are used as the cross-linking cations of the bead. According to TEM (transmission electron microscopy), the size of the immobilized ZVI was as small as a few nanometers. From the surface analysis of the Fe/Pd-alginate, it is found that the immobilized nZVI has the core-shell structure. The core is composed of single crystal Fe(0), while most of irons on the surface are oxidized to Fe(3+). When 50 g/L of Fe/Pd-alginate (3.7 g Fe/L) was introduced to the aqueous solution, >99.8% of TCE was removed and the release of metal from the support was <3% of the loaded iron. The removal of TCE by Fe/Pd-alginate followed pseudo-first-order kinetics. The observed pseudo-first-order reaction constant (k(obs)) of Fe/Pd-alginate was 6.11 h(-1) and the mass normalized rate constant (k(m)) was 1.6 L h(-1) g(-1). The k(m) is the same order of magnitude with that of iron nanoparticles. In conclusion, it is considered that Fe/Pd-alginate can be used efficiently in the treatment of chlorinated solvent.

  • Entrapment of Iron Nanoparticles in Calcium Alginate Beads for Groundwater Remediation Applications

    nZVI has been successfully entrapped in biopolymer, calcium (Ca)-alginate beads. The study has demonstrated the potential use of this technique in environmental remediation using nitrate as a model contaminant. Ca-alginate beads show promise as an entrapment medium for nZVI for possible use in groundwater remediation. Based on scanning electron microscopy images it can be inferred that the alginate gel cluster acts as a bridge that binds the nZVI particles together. Kinetic experiments with 100, 60, and 20mg NO3--N L-1 indicate that 50–73% nitrate-N removal was achieved with entrapped nZVI as compared to 55–73% with bare nZVI over a 2-hour period. The controls, which ran simultaneously, show little NO3--N removal. Statistical analysis indicates that there was no significant difference between the reaction rates of bare and entrapped nZVI. The authors have shown that nZVI can be effectively entrapped in Ca-alginate beads and no significant decrease in the reactivity of nZVI toward the model contaminant (nitrate, in this case) was observed after the entrapment.

In this report, the screening capability of SP-ICPMS is demonstrated in a study of transformations of silver nanoparticles in surface water.

  • Adobe PDF LogoA Risk/Benefit Approach to the Application of Iron Nanoparticles for the Remediation of Contaminated Sites in the Environment

    Iron nanoparticles (NPs) are highly reactive reducing agents and as such degrade organic compounds and change the oxidation state of elements. A concern in the UK is that unreacted iron NPs can spread from the treatment zones and cause harm to human health or the environment. The available information suggests that iron NPs have relatively short lifetimes in the environment before they are inactivated (~6 months as a maximum) and migrate relatively short distances (100 meters) from injection points. The field-scale evidence base is limited and potentially unreliable, however, and the literature offers a range of opinions about reputed iron NP impacts in the field. The available evidence can support a range of interpretations about the potential risks from iron NP use in soil and groundwater remediation, some of which differ from those reached in this 2011 report for the UK Department for Environment, Food and Rural Affairs. Appendix 2 contains 3 case studies of iron nanoparticle field application.
