Abstract:

The metal oxide [Li3Mn0.5Ti0.25O3] was synthesized by solid state reaction crystallization method in certain temperature. It was an inverse spinel type compound metal oxide. The extraction/insertion reaction of this material was studied by X-ray, saturation exchange capacity value and distribution coefficient (Kd) measurement value. In terms of its composition and chemical metrology, this inverse spinel material is very comprehensive; it is worth noting that it can be inserted or extracted by other substitutional ions and changes in lithium and oxygen stoichiometry while maintaining their crystal structure. The metal oxide [Li3Mn0.5Ti0.25O3] is inorganic Li+ exchanger which has an ion-memory capacity. It has high exchange selectivity ability for Li+. This metal oxide can be used to separate or extract Li+ in aqueous solution. The experimental result has confirmed inverse spinel type compound metal oxide which was treated by acid could attain 9.7 mmol‧g-1 Li+ exchanged capacity.
