Synthesis of Iron Oxide Nanoparticle Functionalized Activated
This work reveals the As V adsorption behaviors onto iron oxide Fe3O4 nanoparticles modified activated carbon AC originally developed from biochar BC as a green adsorbent denoted by FAC. Since FAC has abundant surface functional groups and a desired porous structure that is favorable for the removal of As V in contaminated water FAC has greatly enhanced the As V adsorption capacity
Synthesis of ZnO nanostructure using activated carbon for
Activated carbon was modified by oxidation with nitric acid to get carboxylic derivative ACCOOH . Then zinc was loaded on the surface of modified activated carbon by an impregnation method. The ZnO nanostructure was characterized by BET XRD and SEM that confirmed achieving of ZnO nanoparticles with a size of 2131 nm and surface area of
Modified activated carbon with silvercopper mixed oxides

Base modified activated carbonnanoparticle hybrid for water
The sample was then oven dried at 70 C 80 C over 24 h. The base modified AC was termed as KOHAC. Subsequently CuNP was impregnated on the base modified activated carbon by the wet impregnation method. 1 g KOHAC was added to 80 ml of CuNP solution which was stirred at 150 rpm for 24 h at room temperature.
Adsorption of silver nanoparticles modified activated carbon
Activated carbon is an attractive option for such appli ions as a result of its high surface area porous properties and susceptibility to active metal dispersion. Modified activated carbon materials demonstrate very high adsorption capacity for target pollutants and excellent adsorption kinetics .
Model diesel denitrogenation by modified activated carbon
Activated carbon modified with iron oxyhydroxide nanoparticles is a very interesting material that might promote nitrogen interactions with carbon due to the increase in oxygen group density after iron addition.
Arsenic removal by modified activated carbons with iron hydro
The As V adsorption capacity of activated carbons increases after modifi ion with iron due to the presence of iron hydro oxide nanoparticles. The modified activated carbons F400M CAZM and CAPM removed As V at similar concentrations to those found in drinking water lt300 g L1 but F400M was found to be the most efficient
