Abstract The paper presents the conceptual separation process of lithium and cobalt(II) ions from aqueous solution using lanthanum enriched TiO2-ZrO2 hybrid material. The material was synthesized via modified sol-gel method and thoroughly characterized with respect to porous structure, morphology, chemical composition, nature of characteristic functional groups, crystallinity and electrokinetic behaviour. Furthermore, sorptive properties of the obtained hybrid material were indicated towards recovery of lithium and cobalt(II) ions. The influence of such parameters as sorption time, temperature, adsorbate concentration, adsorbent dose and solution pH, on the efficiency of the performed adsorption process was determined. Experimental data collected have shown a high selectivity of the synthesized hybrid material relative to cobalt(II) ions in the presence of lithium ions.
