Potassiumpolytitanate(PPT) with different degree of protonation is proposed as a new kind of inorganic adsorbent for lithium ions recovery from natural aqueous solutions. The phase and chemical composition, as well as the particle size distribution of the sorbents are studied using XRD,XRFanalysis, and laser diffraction. The efficiency of lithium ions recovery and the adsorption process kineticsfor are investigatedusing standard solutions of lithium chloride. The sorption capacity and kinetic
