Synthesis and Its Exchange Capacity for Li+ of Mg0.75Ti1.125O3
A spinel-type metal compound [Mg0.75Ti1.125O3], 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 Mg0.75Ti1.125O3 caused Mg2+ extractions of more than 71%, while the dissolutions of Ti4+ were less than 7.2%. The experimental results have proved that the acid-treated sample has a capacity of exchange 7.5mmol•g-1 for Li+ in the solution. It had a memorial ion-sieve property for Li+.
