Abstract This study investigated the degradation of trichloroethene (TCE) by nanoscale zero-valent iron (nZVI) w/o persulfate (PS) in the absence and presence of ethylenediaminetetraacetic acid (EDTA). In the absence of EDTA, the degradation of TCE obeyed the pseudo-first-order kinetics, and the rate constants increased exponentially with increasing ...

Antibiotics, one of the most abundant contaminants in the natural water systems possess various difficulties to remediate through conventional water treatment methods. Tetracycline (TC) remains one of the most widely used antibiotics for human and veterinary applications because of its broad-spectrum antibacterial activity.

In this study, we demonstrate that surface phosphate modification of nZVI (p-nZVI) could enhance the electron selectivity of Cr(VI) reduction from 6.1% to 31.3%, as estimated by XANES and XPS, and thus promote the Cr(VI) removal efficiency by 4 folds ...

This research studied the synthesis of nanozero-valent iron supported on granular activated carbon (nZVI/GAC) catalyst for degradation of paraquat. The catalyst was synthesized with the ratio between the weight of ferrous sulfate heptahydrate and granular activated carbon (2:1). The prepared catalyst reacted with sodium borohydride

Nanoscale zero-valent iron (NZVI) has been considered as a potential scavenger for U(VI) elimination from aqueous environment. To decrease the aggregation and to improve antioxidation, sulfidation technology and biochar were applied to modify NZVI.

A comparison between field applications of NZVI
2007Despite the use of Nanoscale Zerovalent Iron (NZVI) for the remediation of contaminated aquifers was proposed more than 10 years ago, there’s a wide literature and a good market demand, its application is still limited. The aim of this study is to understand the reason why the number of full scale applications is so small and to systematizes the ...
