The object of this invention was development of a method for the selective absorption of sodium cations in presence of foreign alkali or earth alkali cations with minimal costs and instrumental effort. The process must be scalable, and sodium traces must be sufficiently low for Li-ion battery purposes or other sodium-sensitive applications. It has been found that a certain class of calcinated mixed oxide ceramic material can solve the task. This material is named LAMP herein and defined below. Said LAMP material can be used as an absorber to remove Na+ selectively from a cation containing medium. LAMP stands for the stoichiometry Li1+x+y+zAlxM2-xP3-yO12 where 0 ≤ x ≤ 0.6 and 0 ≤ y ≤ 0.4 and 0 ≤ z ≤ 0.1 and where M is at least one metal selected from the group consisting of Ti, Si, Ge.
