nZVI-responsive biofilm production of Pseudomonas putida under mild nZVI condition

Journal of Nanoparticle Research, 2021
The use of zero-valent iron nanoparticles (nZVI) is an emerging application for environmental remediation. In the present work, the effect of mild nZVI conditions (2.5, 10, and 25 mg L−1) on the bacteria biofilm and growth of both planktonic and sessile cells based on a Pseudomonas putida (P. putida) model was studied. Core shell nZVI nanoparticles (25

The high efficient Sb(III) removal by cauliflower like amorphous nanoscale zero-valent iron (A-nZVI).

Journal of Hazardous Materials, 2022
In this study, cauliflower like amorphous nanoscale zero-valent iron (A-nZVI) was prepared and its performance on the removal of Sb(III) was investigated and compared with that of nZVI. The results indicated that the removal of Sb(III) by nZVI and A-nZVI

Efficient degradation of anthracene in soil by carbon-coated nZVI activated persulfate.

Journal of Hazardous Materials, 2022
The easy passivation defect of nano zero-valent iron (nZVI) greatly limits its application in site pollution remediation. Carbon coating can effectively inhibit the passivation of nZVI, but its effectiveness in the soil is still unknown.

Highly efficient removal of arsenic (III/V) from groundwater using nZVI functionalized cellulose nanocrystals fabricated via a bioinspired strategy.

Science of the Total Environment, 2022
Utilizing nanoscale zero valent iron (nZVI) to purify groundwater contaminated by arsenic species [As(III/V)] is an efficient technology, but the fast and severe aggregation of nZVI limits its practical applications.

Influence of modified biochar supported sulfidation of nano-zero-valent-iron (S-nZVI/BC) on nitrate removal and greenhouse gas emission in constructed wetland.

Journal of Environmental Science, 2022
In this study, the biochar (BC) produced from sawdust, sludge, reed and walnut were used to support sulfidation of nano-zero-valent-iron (S-nZVI) to enhance nitrate (NO3--N) removal and investigate the impact on greenhouse gas emissions. Batch experiment

Inhibition of nZVI Reactivity by Magnetite During the Reductive Degradation of 1,1,1-TCA in nZVI/Magnetite Suspension

Applied Catalysis B: Environmental, 2010
Abstract We demonstrated that the reactivity of nano-sized zero-valent iron (nZVI) can be inhibited by magnetite for the reductive degradation of 1,1,1-trichloroethane (1,1,1-TCA) in nZVI/magnetite suspension under low content of nZVI. A remarkable reductive degradation of 1,1,1-TCA (0.289 h−1) was observed in nZVI (0.01 g/24 mL) suspension in 5 h ...

A novel lignin hydrogel supported nZVI for efficient removal of Cr(VI).

Chemosphere, 2022
A novel hydrogel-supported nanoscale zero-valent iron (nZVI) composite (nZVI@LH) was synthesized by ion exchange and in-situ reduction. The removal efficiency was tested, and the mechanism was also explored.

Graphene-like carbon sheet-supported nZVI for efficient atrazine oxidation degradation by persulfate activation

, 2021
Developing excellent carrier materials for supporting metal-based catalysts is challenging. Herein, a graphene-like carbon sheet (CS) was fabricated from a mixture of corn straw and potassium oxalate (K2C2O4) via a simple one-pot approach.
