The aging of nZVI in oxygenated water yields stable sheet-shaped and well-formed lepidocrocite crystals.
This study investigated the adsorption of PFOA and PFOS by nanoscale zero-valent iron, revealing mechanism enriching understanding environmental remediation.
An angstrom-resolution physical model of nanoscale zero- valent iron (nZVI) is generated with a combination spherical aberration corrected scanning transmission electron microscopy (Cs-STEM) and energy-dispersive X-ray spectroscopy (EDS).
The α-Fe<sub>2</sub>O<sub>3</sub>–rGO materials prepared by one-pot hydrothermal conditions exhibit an excellent capacity to remove MG from water.
The speciation and distribution of Se in the oxide layer nZVI were studied using high-resolution X-ray photoelectron spectroscopy with sputter depth profiling, proved to be dependent.
Dynamic transformation of mineralogical phases and chemical compositions nanoscale zerovalent iron (nZVI) influence its reactivity as well affinity toward contaminants in water solution, because corrosion nZVI under different geochemical conditions alters intermediate products the core–shell structure. In this study, particles aged oxic (nZVIA) over experimental time scales 2, 6, 12, 24, 48, 72 h are reacted with CrO42– [Cr(VI)] solution at pHinitial 4.4. Transmission electron microscopy...
Gas nanobubbles used for water treatment and recovery give rise to great concern their unique advantages of less byproducts, higher efficiency, environmental friendliness. Nanoscale zerovalent iron (nZVI), which has also been widely explored in the field remediation, can generate gas hydrogen by direct reaction with water. Whether nanoscale bubbles be produced enhance pollution removal nZVI system is one significant involved. Herein, we report observations situ generation (HNBs) from More...
