Research on nanoscale zero-valent iron coupled advanced oxidation process for wastewater treatment
Nanoscale zero-valent iron(nZVI) has broad application prospect in the field of water treatment due to its high specific surface area, high reactivity, and strong reduction performance. Four commonly used preparation methods of nZVI were described and compared, including liquid phase reduction, carbothermal reduction, green synthesis and mechanical ball milling. As nZVI had the problems of easy agglomeration and oxidation, four modification methods of nZVI such as load modification, bimetallic modification, vulcanization modification and surface modification were introduced. The mechanism of nZVI coupled with several common oxidants (O2, H2O2, O3, PS, etc.) to remove refractory wastewater was analyzed, and the research trend and development direction of nZVI in the field of water treatment were proposed.
