Environmental remediation with nanomaterials
Research Guide
What is Environmental remediation with nanomaterials?
Environmental remediation with nanomaterials is the application of nanoscale materials, such as nanoscale zero-valent iron (nZVI), to remove contaminants like heavy metals and organic pollutants from groundwater, wastewater, and soil through processes including adsorption, reductive dechlorination, and sequestration.
The field encompasses 24,545 works focused on nanomaterial applications in groundwater remediation, wastewater treatment, heavy metal removal, and environmental cleanup. Key methods include contaminant sequestration, reductive dechlorination using nZVI, and deployment in permeable reactive barriers, with investigations into surface modifications and long-term performance under various conditions. Spectroscopic techniques aid in understanding nanomaterial interactions with pollutants in these systems.
Topic Hierarchy
Research Sub-Topics
Nanoscale Zero-Valent Iron Reactivity
Nanoscale zero-valent iron reactivity studies electron transfer kinetics for dechlorination of chlorinated solvents and reduction of nitroaromatics. Researchers investigate core-shell structure effects, pH dependence, and reactive oxygen species generation.
nZVI Surface Modification
nZVI surface modification enhances mobility and selectivity using polyelectrolytes, polymers, and sulfidation for targeted pollutant removal. Researchers evaluate coating stability, transport in porous media, and long-term efficacy.
Heavy Metal Sequestration by Nanomaterials
Heavy metal sequestration by nanomaterials examines adsorption mechanisms, capacity, and selectivity for Cr(VI), As, and Pb using iron oxides and carbon composites. Researchers apply isotherms, spectroscopic characterization, and regeneration studies.
Permeable Reactive Barriers
Permeable reactive barriers deploy nZVI emplacements for passive groundwater treatment, monitoring longevity and clogging. Researchers model reactive zone hydraulics, byproduct accumulation, and full-scale performance optimization.
Nanomaterial Toxicity in Remediation
Nanomaterial toxicity in remediation assesses ecological risks of nZVI leaching, reactive oxygen species, and bioaccumulation in soil microbes and aquatic organisms. Researchers conduct fate-transport modeling and risk assessment frameworks.
Why It Matters
Nanomaterials enable efficient removal of heavy metals from industrial wastewater, addressing toxicity to meet treatment standards, as reviewed in 'New trends in removing heavy metals from industrial wastewater' by M.A. Barakat (2010), which cites processes reducing contaminants to compliant levels. Nanoscale zero-valent iron particles provide an overview of remediation for chlorinated compounds and metals in groundwater, with Wei‐xian Zhang (2003) noting their high reactivity and surface area for in situ applications. 'Green’ synthesis of metals and their oxide nanoparticles: applications for environmental remediation' by Jagpreet Singh et al. (2018) highlights sustainable production of these nanomaterials for eco-friendly cleanup, including sequestration of pollutants in leachate as detailed by Peter Kjeldsen et al. (2002), where heavy metals form a key pollutant group.
