Reade Advanced Materials - Zero-Valent Iron (ZVI /

2021-5-4  Zero-valent iron (ZVI) has been successfully used for the degradation of a wide range of organic contaminants in groundwaters in recent years. The rate of degradation of contaminants by ZVI may be enhanced by use of nanoscale zero valent iron (nZVI) particles which possess higher surface area than the more widely used granular materials.

FeNX(C)-Coated Microscale Zero-Valent Iron for Fast

2021-3-17  FeNX in Fe single-atom catalysts can be the active site for adsorption and activation of reactants. In addition, FeNX species have been shown to facilitate electron transfer between Fe and the carbon supports used in newly developed metal–air batteries. We hypothesized that the combination of FeNX species with granular zero-valent iron (ZVI) might result in catalyzed reductive ...

Activated peroxydisulfate by sulfidated zero-valent

2020-9-15  To solve this problem, zero-valent iron (Fe 0) has been employed as an alternative to Fe 2+ to activate PDS , . Fe 0 is unstable when it is brought into contact with water and will undergo a series of reactions to form Fe 2+ (eqs. , ) , , , . PDS itself could also oxidize Fe 0 to form Fe 2+ through reaction .

Zero Valent Iron (ZVI) Archives - REGENESIS

2019-6-7  Typically, zero valent iron cannot be applied through well systems. However, due to the small particle size of the zero valent iron, this application was successfully applied through the existing wells. At 3 years post-injection, the contaminant levels remain near zero with the presence of ethene indicating continuous biodegradation.
