Y type nano zeolite (NFA-Y) was synthesized from fly ash by hydrothermal method at low temperature and without adding template. The structural and properties of the materials were characterized using XRD, BET Surface area analyzer and SEM. The results showed that the particle size of NFA-Y about 80 nm, the specific surface area is 508.2 m2 g−1, the pore volume is 0.342 cm3 g−1. The adsorption characteristics of Cs+ in aqueous solution by NFA-Y were studied. The adsorption capacity of the NFA-Y was 167.12 mg g−1 about. The adsorption equilibrium and the kinetic studies showed that the main adsorption mechanism were monolayer coverage and the chemical adsorption plays a dominant role in the overall Cs+ adsorption process.
