In this experiment, the stabilized zeolite molecular sieve was prepared by alkali fusion hydrothermal method, with pretreated fly ash as main raw materials, solid NaOH as cosolvent. The effect of NaOH fly ash ratio, calcination temperature, crystallization time, crystallization temperature and other experimental factors on the structure and properties of the synthetic zeolite was researched. And the crystal type, surface morphology as well as absorbance were characterized by X-ray diffrac-tion (XRD), scanning electron microscopy (SEM), specific surface area (BET) and spectrophotometer, respectively. The re-sults showed that the synthesized zeolite molecular sieve was Na-A zeolite type when the NaOH fly ash ratio was 1.3, the calcination temperature was 600℃, and the crystallization time was 10 h, crystallization temperature was 100℃. Moreover, the specific surface area measured by BET was 97.053 m2/g and in 2 hours the removal rate of methylene blue was 97%, which showed good adsorption performance.
