Abstract: In this study, synthesis of zero valent iron nanoparticles dispersed on alumina by sodium borohydride reduction process was achieved for the removal of arsenic. Structure and properties of ZVI on alumina is investigated using various analytical techniques, for instance FTIR spectroscopy, scanning electron microscopy (SEM) and transmission microscopy (TEM). Dispersing the zero valent iron nanoparticles on alumina enhances the ease of separation of particles after treatment. Adsorption experiments were conducted to study arsenic removal from drinking water by synthesized adsorbent (zero valent iron on alumina) and residual arsenic concentration was analysed by atomic absorption spectrometer (AAS). The arsenic removal efficiency was found to be greater than 70% at neutral pH and have high absorption capacity. The results of experiments show that the synthesised material exhibit high efficiency on water treatment.
