Adsorption of Sb(III) from Aqueous Solution by nZVI/AC: A Magnetic Fixed-Bed Column Study

, 2021
The effectiveness of nanoscale zero-valent iron(nZVI) immobilized on activated carbon (nZVI/AC) in removing antimonite (Sb(III)) from simulated contaminated water was investigated with and without a magnetic fix-bed column reactor.

A comparative study of removal of methyl tertiary-butyl ether (MTBE) from aquatic environments through advanced oxidation methods of H2O2/nZVI, H2O2/nZVI/ultrasound, and H2O2/nZVI/UV

Desalination and Water Treatment, 2016
AbstractThis study compares the efficiency of oxidation with H2O2 and nanoscale zero-valent iron (nZVI)in the presence of ultrasound and that of oxidation with ultraviolet radiation and H2O2/nZVI in the removal of MTBE from aqueous solutions. The effects of some parameters, such as ultrasound, contact time (2–60 min), concentration of hydrogen peroxide
