| Abstract: The ion-exchanger LiMg0.5Mn1.5O4 of spinel type was prepared by the common precipitation/heated crystallization method, and was acid modified. Its properties of ion-exchange for alkali ions such as saturation capacity of exchange, distribution coefficient and the pH titration curve have been determined. LiMg0.5Mn1.5O4 was characterized by X-ray diffraction. These results show that this inorganic ion-exchanger has better remembering and selectivity of ion exchange, and higher capacity of exchange for Li+, the capacity of exchange reaches 32.39 mg·g-1 for Li+. |
