Spinel-type metal oxides, magnesium-manganese- titanium oxide (MgMn0.25Ti0.75O3), was prepared by a coprecipitation/thermal crystallization method. The extraction/insertion reaction with this material was investigation by X-ray, saturation capacity of exchange, and Kd measurement. The acid treatments of MgMn0.25Ti0.75O3 caused Mg2+ extractions of more than 81%, while the dissolutions of Mn4+ and Ti4+ were less than 15%. The experimental results have proved that the acid-treated sample has a capacity of exchange 7.1mmol•g-1 for Li+ in the solution.
