Development of a Novel Iron Based Nanomaterial and its Characterization
1.Introduction Arsenic is a well established contaminant in many of the water sources worldwide. Novel nanomaterials like nano zero valent iron1, magnetite nanoparticles2,3 etc., have been synthesized and applied for the purpose of arsenic remediation in contaminated water. We report here the synthesis and characterization of an aqueous iron oxyhydroxide suspension of nanometric dimension with the objectiveof removing As(Ⅲ) and As (Ⅴ) in aqueous medium. The suspension was dehydrated at room temperature in air, and characterized by XRD, SEM and TEM.The X-Ray diffraction pattern was broad indicating small crystallites size. Particle size could not be resolved well from SEM micrograph while EDAX analysis showed the dehydrated material to contain 40.3 wt.％ iron and 43.7 wt.％ oxygen. TEM bright field image confirmed the nanometric dimension of the particles in the range of 2-10 nm, corroborated by concentric rings, typical of nanoparticles, in the diffraction pattern. The suspension worked well for the removal of As (Ⅲ) and As (Ⅴ) in synthetic water.
