Study of an Inorganic Ion Exchanger Mg0.5Ti1.25O3
The ion-exchanger Mg0.5Ti1.25O3 was prepared by a solid state reaction 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 Mg0.5Ti1.25O3 caused Mg2+ extractions of more than 72%, while the dissolutions of Ti4+ were less than 7.1%. The experimental results have proved that the acid-treated sample has a capacity of exchange 5.4mmol•g-1 for Li+ in the solution.
