The increasing application of iron-based nanoparticles (NPs), especially high
concentrations of zero-valent iron nanoparticles (nZVI), has raised concerns regarding their …

Attachment of engineered and naturally occurring macromolecules greatly affects the
environmental fate and toxicity of engineered nanomaterials (ENMs). A better understanding …

Hexavalent chromium (Cr), one of the most common heavy metals, is widely found in
contaminated soil and groundwater. Nano zero-valent iron (nZVI) is used to treat Cr (VI) in …

Sulfurized nanoscale zerovalent iron (S-nZVI) has been widely reported to be able to quickly
remove heavy metals/persistent organic pollutants, but the limited understanding of the …

Remediation of dense non-aqueous phase liquid (DNAPL), which consists primarily of
chlorinated solvents, is considered a top priority in the field of groundwater decontamination …

In this study a NZVI was prepared by the liquid phase reduction method. The modified NZVI
obtained was characterized by BET, TEM and XRD. The results showed that the iron in the …

Chlorinated aliphatic hydrocarbons (CAHs) have been frequently detected in aquifers in
recent years. Owing to the bioaccumulation and toxicity of CAHs, it is essential to explore …

We conducted a series of flow-through column experiments using aquifer sediment treated
with zero valent iron (Fe 0) with or without active microbial sulfate reduction. The aim of this …

We assessed the potential of zerovalent-iron-(Fe0) based permeable reactive barrier (PRB)
systems for arsenic (As) remediation in the presence or absence of microbial sulfate …

Sulfidated nanoscale zerovalent iron (S-nZVI) has showed higher reactivity towards organic
pollutants and metal ions than nZVI. However, the competitive reaction and electron …
