In this study, Na-A type zeolite with high crystallinity was synthesized hydrothermally from NaAlO₂ and Na₂SiO₃ precursors. The obtained Na-A zeolite was converted into Li-A zeolite through stepwise ion exchange using LiCl solution. During the three-stage exchange process, Na⁺ ions were effectively replaced by Li⁺ ions while maintaining the structural stability of the zeolite framework. The resulting products were thoroughly characterized by X-ray diffraction (XRD) and infrared (IR) spectroscopy. XRD results confirmed that Li-A zeolite retained high crystallinity and predominantly formed lithium aluminosilicate phase. IR spectroscopy revealed shifts in Si–O–Al and Si–O–Si vibrations, indicating the incorporation of Li⁺ ions into the framework cavities. The final Li-A zeolite exhibited high ion-exchange capacity, stable morphology, and selective adsorption properties, making it a promising material for gas separation, catalysis, and electrochemical applications.
