Mechanism of Dissolved Organic Matter Constructing Zerovalent Iron Interfacial Mass-Transfer Channel Combined with Shewanella oneidensis MR-1 To Remove Cr(VI)

ACS ES&T Engineering, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 13, 2024

Nanoscale zerovalent iron (nZVI) is a promising remediation agent for the removal of heavy-metal wastewater. However, nZVI tends to agglomerate and be oxidatively deactivated during reaction, which limits its application. To address problem, this study develops novel modification method regulate reaction interface by introducing fulvic acid (FA), naturally occurring environmental component, synthesis nZVI. FA disrupts circumferential-stress equilibrium nZVI, enhances Kirkendall effect, establishes mass-transfer channels, facilitating outward transfer reducible Fe(II) electrons inward transport surface-adsorbed Cr(VI). The Cr(VI) further enhanced coupling FA-nZVI with Shewanella oneidensis MR-1, reduces Fe(III) hydroxides at interface, thereby preventing accumulation passivation layer that blocks channels. synergistic action channels MR-1 rate 4.7 times, ensuring more than 60% under extreme conditions. By exploring new functions as an organic carbon provides fresh perspective on utilization in ecosystems. Leveraging factors microstructural modulation efficient environmentally friendly approach pollution.
