The ion-exchanger Al1.75Fe1.25(PO4)3 of spinel type was prepared by means of the solid state reaction crystallization method. Its ion-exchange properties for alkali ions such as saturation capacity of exchange and distribution coefficient were determined. Al1.75Fe1.25(PO4)3 was characterized by virtue of X-ray diffraction method. This inorganic ion-exchanger (Al1.75Fe1.25(PO4)3) has the saturation capacity of exchange for Li+ higher than those for other alkali ions, the saturation capacity of exchange for Li+ reaches to 7.1mmol/g, AlFe-720(H) has a higher selectivity of ion exchange for Li+ than for other alkali ions. These result show AlFe-720 (H) has better memory and selectivity of ion exchange, and higher capacity of ion exchange for Li+. It is a kind of prospective ionic sieve for Li+.
