Engineered iron nanoparticles, with sizes smaller than 100 nm, have been of high concern because of their promising capability in environmental remediation. Nanoparticles based on zero-valent iron (nZVI) have the potential not only to migrate in the environment and interact with pollutants but also influence the living organisms by direct impact or by changes of groundwater parameters. The basi...

The effect of zero-valent iron nanoparticles (nZVI) addition on methane production during anaerobic digestion pig slurry was assessed. Experiments were conducted using two experimental set-ups: batch and long-term continuous operation at a fixed nZVI dosage. Two different temperature ranges (mesophilic thermophilic) Biogas content monitored, the specific methanogenic activity biomass oxidation ...

Zerovalent iron nanoparticles (nZVI) are becoming one of the most widely recommended nanomaterials for soil and groundwater remediation. However, when nZVI injected in flow, behavior (mobility, dispersion, distribution) is practically unknown. This fact generally results use enormous quantities them at field scale. The uncertainties on effective volumes reached from plume because their tendency...

Fluoroquinolone antibiotics attract increasing attention in the water treatment field because of potential adverse effects on aquatic ecosystems and human health. The graphitic carbon nitride (g-C 3 N 4 ) based photocatalysis has been demonstrated as an economically feasible environmentally benign process to control these persistent contaminants. In this study, a new visible-light-driven reduce...

contaminated groundwater by gasoline spill is a worldwide environmental problem. gasoline contains methyl tert-butyl ether (mtbe) and benzene, which are the chemicals of concerns (cocs) among the gasoline components. mtbe is highly water soluble and has a low henry’s law constant and low soil adsorption co-efficient. therefore, mtbe can easily move through the soil and then accumulate, distribu...

iron (in zero-valent and oxide forms) is used to remove numerous organic and inorganic contaminants in environment. however, there are few reports, especially in nano scale, on the remediation of heavy metals contaminated soils using zero-valent iron in the literature. in this study, the effect of iron on the availability of heavy metals was evaluated in a calcareous soil spiked with cadmium, z...

Non-steroidal anti-inflammatory drugs (NSAIDs) and endocrine disruptors (EDCs) are among the most important categories of contaminants emerging concern (CECs), many advanced technologies have been developed for their elimination from water wastewater, including nano-zero valent iron (nZVI). This study investigates performance nZVI synthesized green tea extracts incorporated into a cationic resi...
