Basic Zeolites: Structure, Preparation and Environmental, pp. 51-66treatment of the zeolite in alkaline medium, in order to remove the Si atom from the structure. Add to reduce the Si/Al ratio, an increase in the mesoporosity of the zeolites is obtained, thus favouring the diffusion in the pores and the access to the basic sites generated. This treatment increases the acid site density of the.الزيوليت الكسارة الأساسية,FTIR study of CO adsorption on basic zeolites - Journal of Materials .FTIR spectra of CO adsorbed at low temperatures on CsX and KX zeolites, unlike those for CsZSM5 or NaX, reveal bands at wavenumbers below the position of the free molecule. In accordance with the electrostatic model, the bands are attributed to molecules which form side-on complexes with basic framework oxyg.
