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

Drastically inhibited nZVI-Fenton oxidation of organic pollutants by cysteine: Multiple roles in the nZVI/O2/hv system

Journal of Colloid and Interface Science, 2021
The influence of l-cysteine, a common aliphatic amino acid, on the zero-valent iron (nZVI)/O2 photo-Fenten degradation of rhodamine B (RhB) was investigated in this study. The oxidation rate of RhB in the nZVI/O2/hv system was 91.2% after 40 min under the illumination and oxygen conditions and pH of 3, but when cysteine was introduced into the system ...

Groundwater geochemical constituents controlling the reductive dechlorination of TCE by nZVI: Evidence from diverse anaerobic corrosion mechanisms of nZVI

Chemosphere, 2021
The corrosion mechanisms of nanoscale zero-valent iron (nZVI) vary with different geochemical constituents, which affect the reductive dechlorination process of trichloroethylene (TCE). In this study, the effect of nZVI anaerobic corrosion on the reductive dechlorination of TCE with different groundwater geochemical constituents (Ca2+-SO42-, Ca2+-HCO3-,

Field-scale investigation of nanoscale zero-valent iron (NZVI) injection parameters for enhanced delivery of NZVI particles to groundwater

Water Research, 2021
The effects of the injection parameters on delivery of nanoscale zero-valent iron (NZVI) to contaminated groundwater were investigated. The first two NZVI injections (gravity injection at low flow rates) resulted in NZVI being poorly mobile and gave total cumulative mass recoveries at the monitoring wells of 1.07%-2.43%. NZVI reached some wells (KDMW-3,
