Abstract: To solve the problem of selectively removing harmful components in cigarette smoke, aluminium oxide and hydroxyl aluminium pillared montmorillonites were prepared. XRD, SEM, N2 physical adsorption, acidic position analysis using ammonia as probe molecule, differential thermal gravity and addition experiment in cigarette filter were carried out for material characterization. The results indicate that distances between (001) crystal faces of aluminium pillared montmorillonites are increased, and the slot pores appear. Diameters of most particles are around 10 μm. An amount of Lewis acid position located on the surface. Adsorption of the components in smoke proves that aluminium pillared montmorillonite can remove phenol, croton aldehyde, hydrogen cyanide and ammonia in some degree. The hydroxyl aluminium pillared montmorillonite added can increase the mass fraction of water about 45% in the smoke. The aluminium pillared montmorillonite is a potential adsorption materials with both water retention and adsorption used in cigarette filter.
