摘要

Compound Al_(1.5)Fe_(0.5)(PO_4)_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 8.7mmol/g for Li~+. It had a memorial ion-sieve property for Li~+.
