Research Abstract

From the viewpoint of the environmental protection in order to remove arsenic from environmental water such as groundwater, magnetite nanoparticles were synthesized from Fe(II, III) ions solvated in a mixed polar solvent/water solution. Nanoparticles with sharp particle size distribution were synthesized and the nanoparticles have high surface area and the adsorptive performance was enhanced.
