Removal of arsenate and selenite from aqueous solution using nano-amorphous iron-titanium hydrous oxide
Original language description
Metaloids such as selenium (Se) and arsenic (As) are among the most important environmental contaminants affecting environment and human health. The Fe-Ti hydrous oxide was synthesized and used as an adsorbent for removal of arsenate (As(V)) and selenite(Se(IV)) from aqueous solution. The new synthesized adsorbent was investigated using Transmission Electron Microscopy (TEM), X-Ray powder diffraction (XRD), the Brunauer-Elmet-Teller nitrogen adsorption technique (BET-N2 adsorption), Fourier transform spectroscopy (FTIR), thermogravimetric analysis (TGA) and batch experiments were carried out to determine its adsorption properties. It is shown that the adsorbent was nano-amorphous hydrous oxide with high specific surface area of 230 m2/g. The increaseof pH had negative effects on the adsorption of the As(V) and Se(IV), but Se(IV) was more sensitive to pH changes than that of As(V). Kinetic data was well fitted by a pseudo second-order model. Langmuir isotherms gave the best descriptio
