摘要：

This paper presents a study of the equilibrium of SO2 adsorption on Y type zeolites, for which the the X-ray diffraction spectra were also carried out. The adsorption isotherms of sulphur dioxide on two HY and NaY zeolites were determined depending on the pressure and temperature of the adsorbate. The adsorption isotherms were calculated using Langmuir and Freundlich models, which were subsequently compared to the experimental isotherms. It was found that SO2 adsorption on Y zeolites can be described by the Freundlich model, and that the NaY zeolite is a better sorbent than HY.
