Abstract
Carbon-doped TiO2 (C-TiO2) was fabricated using a facile hydrothermal treatment. It was applied as an adsorbent to remove Pb(II) from the aqueous solution. The morphology and properties of the adsorbent were characterized with TEM, XRD, SAED and XPS. Furthermore, the applicability of Langmuir isothermal model for Pb(II) onto C-TiO2 was examined. The adsorption capacity of the adsorbent and the determination of Pb(II) were evaluated with ICP-MS. The maximum adsorption capacity is 28.7 mg g-1, and this method has broad application prospects in areas of environmental purification.
