| Abstract |
In this research, the adsorption potential of lithium ions (Li+) by pure titanate nanotubes (TNTs) functionalized TNTs was examined. We used simple hydrothermal method for fabricating TNTs at 130 oC and these synthesized TNTs were functionalized by different OCs including urea, melamine and polyacrylonitrile using titanium (IV) oxide powder as a precursor via impregnation approach. The crystallinity, morphology and functional group properties of prepared adsorbents were characterized. The Li+ adsorption mechanism considered as an ion exchange reaction among Li+ ions and ions exist in an interlayer of pure and functionalized TNTs. Different kinetic models have applied on equilibrium experimental data to determine the rate and nature of adsorption process. The recovery of Li+ ions was done by using hydrochloric acid as an extracting agent with three repeated cycles. The presented study concluded that prepared adsorbents having good potential to adsorb and desorb Li+ ions from aqueous solution with slight reduction in capacity due to organic compounds impregnation. |
