Selective Sodium Removal from Lithium Chloride Brine with Novel Inorganic Ion Exchanger Li_1.4Al_0.4Ti_1.6 (PO₄)₃

Abstract:

The powder of Li_1.4Al_0.4Ti_1.6 (PO₄) ₃ has been synthesized by a solid phase reaction between Li₂CO₃, Al₂O₃, TiO₂ and NH₄H₂PO₄. Sodium removal was studied in an extensive series of tests involving different ionic exchange process variables such as time and temperature. The results indicate that the Na/Li ion exchange reaction rate increased obviously with increasing temperature, and the Na/Li ion exchange kinetics process of Li_1.4Al_0.4Ti_1.6 (PO₄) ₃in lithium chloride solution could be shown approximately by the equation of JMAK. Furthermore, it is concluded that the Na⁺-removed materials obtained from NASICON-type ceramics synthesized can serve as selective Na⁺ absorbent due to its high selectivity and larger ion exchange capacity.
