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+.
