Results on As(V) removal in the presence of oxygen using the zerovalent iron technology with commercial ironnanoparticles (NanoFe1) are presented, showing the effect of (NanoFe1) mass, UV light and addition of humic acids. The nanosized iron particles (NZVI) were characterized in their particle size, surface area...
