Nanoscale zero-valent iron (nZVI) settled slowly and incompletely in a nano-iron reactor (NIR) in wastewater treatment, and the effluent quality and processing capacity of nZVI were degenerated. Herein, three types of polyacrylamide (PAM), anionic-APAM (nZVIAPAM), cationic-CPAM (nZVICPAM), and nonionic-NPAM (nZVINPAM)) were applied to modify the nZVI ...

In most instances, there exists an inaccuracy in interpretation of adsorption/reduction of substances using linear technique as it can only provide an approximate value of the measured parameter; the specific adsorption rate. This paper provides for the first-time modelling of the effect of nZVI/BC, nZVI and Biochar (BC) on the adsorption/reduction of ...

Nanoencapsulation of arsenate with nanoscale zero-valent iron (nZVI): A 3D perspective
Science Bulletin, 2018The principal forces driving the efficient enrichment and encapsulation of arsenic (As) into nanoscale zero-valent iron (nZVI) are the disordered arrangement of the atoms and the gradient chemical potentials within the core-shell interface. The chemical compositions and the fine structure of nZVI are characterized with a combination of spherical ...

Stabilization of nanoscale zero-valent iron in water with mesoporous carbon (nZVI@MC)
Journal of Environmental Sciences, 2019Two challenges persist in the applications of nanoscale zero-valent iron (nZVI) for environmental remediation and waste treatment: limited mobility due to rapid aggregation and short lifespan in water due to quick oxidation. Herein, we report the nZVI incorporated into mesoporous carbon (MC) to enhance stability in aqueous solution and mobility in ...

Nowadays, many researchers have studied the environmental application of the nanoscale zero-valent iron (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, it was investigated to immobilize nZVI

Feasibility of nanoscale zero-valent iron (nZVI) for enhanced biological treatment of organic dyes
Chemosphere, 2019Biodegradation of recalcitrant organic contaminants such as organic dyes is a fundamental challenge in wastewater treatment. We report herein the integration of nanoscale zero-valent iron (nZVI) with membrane bioreactors (nZVI-bio system) to achieve enhanced degradation of Congo red (CR) in wastewater.

Reduction of Cr(VI) by Nanoscale Zero Valent Iron (nZVI): The Reaction Kinetics
2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010Increasing evidence suggests that nanoscale zero valent iron (nZVI) is one of best materials for the treatment of heavy metal ions in water. In this work, the reduction of Cr(VI) by nZVI was investigated. Laboratory experiments with varied Cr(VI) concentrations and nZVI doses were performed.
