The adsorb model of formic acid on NaX derived from TPD was discussed. It was showed that the adsorb sites were various exposed framework O^2- centers bearing different basic intensity and spatial resistance. The h-peak was attributed to O^2- near S_Ⅲ in supercage and l-peak to O^2- near S_Ⅱ in β-cage of faujusite zeolite. The model can explain the experimental results. Meanwhile, a relative standard of basic intensity based on TPD of formic acid was founded.
