Iron Nanoparticles, especially Nanoscale Zerovalent Iron (NZVI) with different Brunauer-Emmett-Teller (BET) specific surface areas, ranging from 13 to 51m~2/g, has been successfully synthesized. The main advantages of NZVI are its high reactivity for the complete removal of toxic pollutants, such as bromate and arsenic; and high potential for introducing iron nanoparticles directly into contaminated water phase and groundwater area. Comparing to commercial micro-size zerovalent iron, synthesized NZVI is more reactive due to its high specific surface area and high dispersivity. The reactivity of synthesized NZVI was observed by investigating the effects of operational parameters on reduction of bromate, our target contaminant, from water state.
