Summary: The study demonstrates that Sulfidated nanoscale zero-valent iron (S-nZVI) can efficiently remove Cd from soil by converting it into less available forms, with minimal impact of soil pH on the immobilization of Cd. Cd was successfully enriched on S-nZVI with distribution closely related to Fe, S, and O, and CdO and CdS were identified as key products for Cd immobilization in soil.

Summary: The core-shell structure of nanoscale zero-valent iron (nZVI) has been shown to provide multiplex solution and surface chemistry for reliable and high-efficiency enrichment and separation of uranium from low-level sources. Treatment of uranium-tailings wastewater in continuous-flow reactors resulted in reacted nZVI with high uranium content and treated wastewater with significantly reduced uranium concentration. This research further supports the cost-effective use of nanotechnology for pollution control and resource recovery.

Summary: The study demonstrates that nZVI can effectively remove U(VI) from strongly alkaline solutions in anaerobic conditions, with a reduction efficiency of up to 95.5%, but the efficiency drops significantly in aerobic conditions due to oxidation and desorption processes. This offers new insights into the mechanisms of U(VI) interactions with nZVI in alkaline media and provides a potential approach for uranium recovery from spent nZVI.

Summary: The spatial configuration of antimony complexes has a significant impact on the removal rate, with Sb(III) showing a higher reaction rate constant than Sb(V). The rate-limiting step is identified as Fe-O bond cleavage, with Sb(OH)3 favoring this process with lower energy barrier compared to Sb(OH)6. These findings suggest a new perspective on nZVI reactions with oxyanions like arsenic and selenium, highlighting the importance of complex spatial configurations in metal(loid) separation.

Summary: This study modified microscale zero valent iron (mZVI) with hydrophilic sodium carboxymethyl cellulose (CMC) using a mechanical ball milling method, referred to as CMC-mZVI, and compared its phosphate removal performance with that of mZVI. The results showed that the crystalline structure of mZVI did not change significantly after ball milling, and CMC could be adsorbed on the surface of mZVI. The phosphate removal percentage of CMC-mZVI was 99.99% within 360 minutes, much higher than that of mZVI (75.23%). This study provided an environmentally friendly and effective method to improve the reactivity of commercial mZVI powder and contribute to the wide application of mZVI technology in environmental remediation.

Summary: This study investigates the effects of sulfate and phosphate on the removal kinetics of hexavalent chromium (Cr(VI)) by different nano zero-valent iron materials. The results reveal that sulfate promotes the reaction while phosphate inhibits it. When both sulfate and phosphate are present, the inhibition effect of phosphate is stronger than the promotion effect of sulfate. This study provides new insights into the efficient removal of Cr(VI) from contaminated water using nano zero-valent iron.

Summary: This paper investigates the simultaneous removal of arsenite and arsenate from groundwater using zero-valent iron nanoparticles (nZVI). The results show that nZVI can efficiently remove both species, and practical application also yields good results. The presence of other coexisting ions, such as phosphate and carbonate, affects the removal efficiency.

Summary: Nanoscale zero-valent iron (nZVI) is a promising disinfection tool for pathogenic enteric viruses. The resistance difference between bacteriophages to nZVI is not well understood. This study found that PhiX174 bacteriophage exhibited stronger resistance to nZVI compared to MS2 bacteriophage. The damage to viral surface proteins and nucleic acids played a role in bacteriophage inactivation.
