Higher environmental standards have made for the removal of arsenic from water, an important problem for environmental engineering. Iron oxide is a particularly interesting sorbent to consider for this application. Its magnetic properties allow relatively routine dispersal and recovery of the adsorbent into and from groundwater or industrial processing facilities; in addition, iron oxide has strong and specific interactions with both As (III) and As(V). Finally, this material can be produced with nanoscale dimensions, which enhance both its capacity and removal. The present study focuses on iron-oxide based complexes that were found to adsorb arsenic from water. Their composition, morphology, magnetic behaviour and potential were studied by Fourier Transform Infra-Red (FTIR) Spectroscopy, X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Transmission Electr..
