The Synthesis and Ion-Exchange Property of Li⁺ Memorized Inverse Spinel Al_0.75Fe_1.25(PO₄)₂

Abstract:

Compound Al_0.75Fe_1.25(PO₄)₂, a inverse spinel-type metal compound, was prepared by a solid state reaction crystallization method. The Li+ extraction/insertion with this material were investigated by X-ray, FT-IR spectroscopy, and Kd measurement, The chemical analysis showed that the Li+ extraction/insertion be progressed mainly by an ion-exchange mechanism. The acid treated samples had an ion exchange capacity of 4.0mmol/g for Li+. It had a memorial ion-sieve property for Li+.
